Safari "stable" consistently crashing on new pointerevents test

[jugglinmike]

Safari 12.1 has failed to upload results for /pointerevents/pointerlock/pointerevent_movementxy.html since the introduction of that test on 2019-06-20.

https://wpt.fyi/results/pointerevents/pointerlock?sha=9c6304b&label=master&product=chrome%5Bexperimental%5D&product=edge%5Bexperimental%5D&product=firefox%5Bexperimental%5D&product=safari%5Bstable%5D

I observed this from the results collection project via the following WebDriver error:

WebDriverException: not implemented (501): Input sources with a pointerType of 'touch' are not currently supported.

but I have not yet researched the Azure Pipelines logs produced by the corresponding collection attempt from this project.

@burg @grorg @youennf do you who might be able to take a look at this?

@graouts may be interested.

Hi! I’ve been writing the WebKit Pointer Events implementation. How can i get set up to run the program that encounters this issue?

[foolip]

@jugglinmike do you have the command line handy for what reproduces this?

[foolip]

I don't believe this is urgent, but something we should resolve. Assigning to Mike to give repro steps for @graouts.

Hi, @graouts! I can consistently reproduce this on a Mac Mini running High Sierra and Safari 12.

macOS: 10.13.6
Safari: Version 12.0.1 (13606.2.100)

https://web-platform-tests.org should have all the information necessary to get WPT running on macOS (if it doesn't, I'll be happy to help you and extend the docs).

Once that's set up, the following command should demonstrate the problem:

$ ./wpt run --no-pause safari pointerevents/pointerlock/pointerevent_movementxy.html 

Here's the output I observe on my system

Cc'ing @burg who might know something about the exception raised here.

I can reproduce the hang locally on Catalina + Safari 13, investigating now.
