Comment 2

[Chris Peterson [:cpeterson]]

Agi says GeckoView doesn't seem to be responding to the test case's hidden = false.

Is this bug reproducible in GeckoViewExample?

We should fix this soon in case its a webcompat issue. Tentatively tracking for m101.

Comment 3

[Chris Peterson [:cpeterson]]

This fix would be nice to have for 101, but it's a lower priority than other bugs we're tracking for 101.

Comment 4

[Chris Peterson [:cpeterson]]

Makoto says this bug looks like a timing issue between the focus change and showing the select picker menu. The fix will require some DOM code changes.

This is a kind of bug 1263887 for GeckoView.

We should close prompt then re-open it when child nodes in <select> element
is modified.

No need to uplift to Beta 101. Fenix will need to fix https://mozilla-hub.atlassian.net/browse/FNXV2-19764.

Moving some focus bugs to the new GeckoView::IME component.
