Do we know if this is a regression from 55?

Using the Mozregression tool, I have found a regression window:

[Liz Henry (:lizzard) (relman/hg->git project)]

Too late for 56 but we could still take a patch for 57.

Comment 4

[Mike Taylor [:miketaylr]]

Maire, should we try to find a new owner for this one?

Comment 5

[Maire Reavy [:mreavy]]

I don't have a new owner for this at this point.  I also am moving this to a P3.  It's officially a regression, but it's not a critical use case, and we've been living with it since 52.  The biggest impact may be to a11y use cases.  If someone wants to advocate for this one, please chime in.

Closing this as WFM as it is no longer reproducible with our latest nightly build 132.0a1 (2024-09-27) using Win 10 and macOS 11.
