Hi Team,

While going through Blink's commit, I came across another issue, where we lost selection if click on label while Firefox Nightly 115 and Chrome Canary 116 does not.

Testcase: https://jsfiddle.net/aqwnsfzt/

^ Select on 'Selection' and then try to select 'label' and you will lose selection in Safari 16.5

Blink Commit: https://src.chromium.org/viewvc/blink?view=revision&revision=171470

WebKit Source: https://github.com/WebKit/WebKit/blob/b37f820dae2abeffca68dc3c9ec6831d8b16f370/Source/WebCore/html/HTMLSelectElement.cpp#L1329

Doing local testing, it does fix the issue and don't fail any test in /fast/forms/select and imported/w3c/web-platform-tests/html/.

We might need to skip it on iOS (test case).

Just wanted to raise, so we can fix it.

Marking this as 'BrowserCompat' as well.

Thanks!
