[Problem/Bug]: <select> dropdown menu gap mouseout issue

[thdoan]

What happened?

In Microsoft Edge, there is a gap between the <select> dropdown menu and its options when you expand the menu:

This can lead to issues with the mouseout event where the user is not able to select the menu options using the mouse because the menu closes prematurely.

Importance

Important. My app's user experience is significantly compromised.

Runtime Channel

Stable release (WebView2 Runtime)

Runtime Version

Repro steps

1. Go to https://jsfiddle.net/thdoan/kev4Lsha/6/
2. Select a menu option.
3. Observe the issue.

Expected behavior

The background should NOT change to red when you select an option, but it does because of the gap. Try following the steps above in Chrome -- you should see that Chrome dropdown menus have no such gap, hence do not suffer from this bug.

Thanks for reporting this issue. I can reproduce in the Edge Browser, and I am trying to find the relevant team.

I do want to point out that this is actually the Edge WebView2 repository,. I saw that you came from the Edge Extension Repository after being redirected to post here, which is unfortunately a wrong advice. There's no GitHub repository for the Edge Browser at the moment, and the best way to report Edge Browser issues in the future would be through the send feedback feature:

@victorhuangwq I reported the issue using this method many months ago, but never got a response. Since reporting issues through Edge feedback doesn't have a feedback loop (ironic), it's hard to know if the thing you reported is being looked at. 😅 Thank you for passing this along to the relevant people.
