This has an increased frequency on windows at least, Emilio can you please take a look?
Thanks!

Comment 4

[Emilio Cobos Álvarez [:emilio]]

I haven't been able to repro this after bug 1896763. However, is this test really useful? It's testing for an event-from-input attribute which seems Gecko specific and barely known / tested. Maybe we can remove this attribute altogether?

Comment 6

[James Teh [:Jamie] (away returning 14 Apr)]

It's slightly possible JAWS uses this, though I doubt it since we don't support it for cached Accessibles from content processes and I would've thought we'd have seen problems by now if it did.

That said, even if this attribute isn't used directly, it comes from an IsFromUserInput flag on a11y events which must be wrong in this case. Android at least does check this in a few places.

Since it was filed this has already picked up 154 total failures: https://treeherder.mozilla.org/intermittent-failures/bugdetails?startday=2024-05-11&endday=2024-05-18&tree=trunk&failurehash=all&bug=1896599
It should be disabled on a11y if not fixed soon. Thank you.

Comment 10

[Emilio Cobos Álvarez [:emilio]]

Attachment: Bug 1896599 - Remove event-from-input support. r=Jamie!

As per the comments it isn't supported with cache-the-world on, it's
barely documented if at all, and a test for it seems to be failing
without me being able to reproduce it at least (tried on both windows
and Linux).

I don't think it's worth digging too much more into it. My guess is a
reentrant / differently timed a11y event caused by my scheduling
changes, or so, which would override sEventTargetNode or the other
static bool.

The test has ~always failed on macOS too...
