Comment 1

[Nazım Can Altınova [:canova][:canaltinova on phabricator]]

I don't think it's regressed by bug 1954675. We added this test in bug 1908308, so it's likely that it's a failure in some certain platforms/configurations.

What do you think Julien? It's failing on opt-mochitest-devtools-chrome-a11y-checks dt1, so it's possible that it's a failure only when the a11y checks are enabled.

Comment 2

[Julien Wajsberg [:julienw]]

Yeah I believe so.
At least bug 1954675 is extremely unlikely.

I'm gonna have a look.

Comment 3

[Julien Wajsberg [:julienw]]

Attachment: Bug 1955997 - Use synthesizeMouseAtCenter instead of sendMouseEvent so that the interactive element is used r=canaltinova

Previously we were using EventUtils.sendMouseEvent on a <panel-item>,
but that element isn't accessible. By using synthsizeMouseAtCenter
instead, Firefox will use the deepest element in the tree, which is the
button in this case.

[agoloman]

It was backfills that showed it was regressed by 1954675.

Comment 6

[Julien Wajsberg [:julienw]]

(In reply to agoloman from comment #5)

It was backfills that showed it was regressed by 1954675.

I see, but this makes no sense :-) there must be another bug somewhere.
