1949641 - Port mitigations for Windows 11 Suggested Actions to MsaaAccessible/ia2AccessibleText

Status: RESOLVED FIXED

(Core :: Disability Access APIs, task)

Description

[James Teh [:Jamie]]

Bug 1798098 implemented some mitigations for Windows 11 Suggested Actions in AccessibleHandler. However, AccessibleHandler was removed as part of Cache the World and these mitigations were never ported across.

I discovered this while investigating bug 1876192. It turned out that fixing this did not address bug 1876192, but I think it makes sense to reinstate these mitigations while Suggested Actions still exists and we have no other workarounds.

Note that the original instantiation mitigations in bug 1774285 still work, as they weren't in AccessibleHandler.

Attachment: Bug 1949641: Port some mitigations for hangs caused by Windows 11 Suggested Actions to MsaaAccessible/ia2AccessibleText.

These mitigations were implemented in AccessibleHandler in bug 1798098.
However, after CtW, AccessibleHandler no longer exists and these mitigations weren't ported across.

Curious. I can't reproduce this locally, nor can I fathom how this patch could have that impact even on CI.
