This adds a few things:

  • A closedby attribute that can be used to control the light dismiss behavior of dialogs:

    1. <dialog closedby=none> - no user-triggered closing of dialogs at all.
    2. <dialog closedby=closerequest> - user pressing ESC (or other close trigger) closes the dialog
    3. <dialog closedby=any> - user clicking outside the dialog, or pressing ESC, closes the dialog. Akin to popover=auto behavior.
    4. <dialog> - i.e. no closedby attribute - default/old behavior. Behaves like closedby=closerequest for modal dialogs, and closedby=none for modeless dialogs.
  • This PR also (per the request) adds a dialog.requestClose() which fires the cancel event, and then (if that isn't cancelled) fires the close event and closes the dialog.

  • I also consolidated the "light dismiss" activities into one algorithm, which will need to be called by Add popover light dismiss integration w3c/pointerevents#460 if that ever gets some attention.

This is exciting! Unfortunately I am going OOO for a week starting ~now, so won't get a chance to review too soon. Hopefully others will be able to help with some reviews, but I would like to get a chance to carefully review the close watcher integration, etc. before this lands.

Would you mind commenting on what approach you took to the mutability of the closedby attribute? We discussed that a bit in #9373, and I think we came up with a tentative proposal, but I'm not sure it was battle-tested.

Looks like CloseWatchers get a mutable enabled value, which is toggled whenever closedby is set to the applicable values - when false it skips the events and returns early. IMO this seems to nicely side-skirt the stacking issues around mutation of the attribute without adding lots of complexity in either the consuming elements and/or having some messy algorithms to insert mid-way into a stack.

That's totally fine - no rush. I did this one in the opposite order that I usually do: spec first, prototype after. So I'm moving on to prototype it now, which might reveal other flaws. But I thought since @lukewarlow had gotten the spec into such decent shape, that I'd clean it up and open the PR in case folks saw other flaws there that I could address in the prototype.

As @keithamus said, I just kept what @lukewarlow did in the original PR, and used a new enabled state on CloseWatcher. I haven't implemented that yet, but it seems reasonably straightforward. But let me know if you see any flaws.

There's very inconsistent spelling of states here. They should match the capitalization and words of how they are introduced. And should typically be followed by the word state (though that's not linked).

Also, perhaps the statement of fact is better as a note?

Yep, I agree. I fixed them all up, I think. Please let me know if you see any others I missed. All are now lowercase.

Also, perhaps the statement of fact is better as a note?

Sorry - can you help me understand this? Which "statement of fact"?

1. The prior implementation ignored the argument to requestClose.
   With this CL, requestClose(string) stores away string and then
   returns it from the CloseWatcher close event.
2. If the dialog's closedBy state is None (either explicitly or
   through the "Auto" state), requestClose throws an exception.

I also added a more significant set of tests for requestClose() in
all states.

This goes along with recent discussion about throwing exceptions if
requestClose() is called when the dialog isn't in the right state,
relative to closedBy:

1. The prior implementation ignored the argument to requestClose.
   With this CL, requestClose(string) stores away string and then
   returns it from the CloseWatcher close event.
2. If the dialog's closedBy state is None (either explicitly or
   through the "Auto" state), requestClose throws an exception.

I also added a more significant set of tests for requestClose() in
all states.

Automatic update from web-platform-tests
Add dialog light dismiss behavior (the actual click outside part) 5/5

This adds to the prior CLs to actually allow "click outside" to
function as a light dismiss trigger.

Sorry for the big delay! Overall this looks good, with the only really substantial suggestion being to move to making enabled an algorithm to avoid the attribute changed steps.

Do you have a link for the tests? I've found that writing comprehensive-feeling tests for close watcher stuff is hard (as you want to test at least two, sometimes more, nested). And then you have all the permutations of attribute values, what if someone modifies the attribute while it's closed, etc. In my experience, without tests it's quite difficult to make sure the behavior is reasonable.

For example, it'd be worth testing (maybe interactively, instead of in WPTs, at least at first) that you get reasonable user behavior in situations like one closedby=none dialog sandwiched in the middle of two closedby=any dialogs.

What is the reasoning for this reordering?

Oh, I wasn't sure about that, thanks for asking. I don't think the ordering of these two steps matters, and it just seemed more logical to me to check first whether it was connected, and then check for a fully active owner document. I can put it back - no big deal.

Thanks for the very thorough review! I think I got everything, but let me know what I missed or did incorrectly.

No problem, and thanks again!

For example, it'd be worth testing (maybe interactively, instead of in WPTs, at least at first) that you get reasonable user behavior in situations like one closedby=none dialog sandwiched in the middle of two closedby=any dialogs.

So I've written tests for several levels of "nesting", including popover/dialog/popover/dialog with mixed modal/modeless dialogs (that's the -complex test). I also added just popover/dialog with different values of closedby (that's the -simple test). But I didn't include closedby permutations in the complex test. I can do that, if you think it'd be helpful.
