hi Team, While looking into some obscure bug in Safari 'New Bug' category, I stumbled upon on totally different so I am raising this as another bug. Test Case: https://bokand.github.io/frameset.html Steps to reproduce: 1) Open above URL 2) Click on green area to make it inactive and change to red 3) Go to frame border (via mouse cursor) Actual Result: Cursor is changed to resize while it is disabled. Expected Result: Cursor should not change. >> Chrome Canary 123 works as expected while Firefox Nightly 124 is broken and allows resizing even after clicking on 'frame' area. __ Just wanted to raise so we can fix it. Only web-spec, I can find around is: https://drafts.csswg.org/css-ui/#default-style-sheet /* Though FRAME resizing is not directly addressed by this specification, the following rules may provide an approximation of reasonable behavior. */ /* frame { resize:both } frame[noresize] { resize:none } */ ___ Just wanted to raise so we can see what we can do. Thanks!
