What specific section or headline is this issue about?

From Note: until but not including Specification.

What information was incorrect, unhelpful, or incomplete?

It seems at least modern Chrome does correctly call finally in the specified circumstances.

Assuming this is the case in all modern browsers and is perhaps even specified as such,
the corresponding content should be removed.

What did you expect to see?

No warning about an obsolete issue, assuming it actually is.

Do you have any supporting links, references, or citations?

Someone should check what the relevant spec says, I'm too busy, sorry.

Do you have anything more you want to share?

No response

[Josh-Cena]

This is a very recent change whose spec isn't even merged: tc39/ecma262#2600 V8 issue fixed in April, but neither of the two other engines have caught up. We need to wait some more, and this would need compat data.

It's still an issue at least in firefox
Currently v133

[vzexadel]

nodejs has this issue being fixed only for v23 which is not LTS
