• Status: RESOLVED
• Resolution: FIXED
• Component: Forms

Hi Team,

This is another failing test case in Safari 16.5 from Blink:

Test Case: http://jsfiddle.net/AERe6/

^ Select option 1 to 5 and without releasing mouse, go outside listbox and release, it will not fire any 'OnChange' event like of Chrome Canary 116 and Firefox Nightly 115.

Blink Commit (For test): https://src.chromium.org/viewvc/blink?view=revision&revision=164563

Blink Commit (For Change): ^ Only do in 'AutoscrollController.cpp' because other got revert and test passed without HTMLSelectElement.cpp changes as per Blink bug.

WebKit Source: https://searchfox.org/wubkat/source/Source/WebCore/page/AutoscrollController.cpp#80

________

Just wanted to raise so we can fix it and if we don't then at least we can document or understand rationale.

Thanks!
