Reported 2006-12-23 05:50:32 PST
In Safari, <INPUT> and anchor (<A>) elements within a block that has opacity applied to it will not receive the treatment (blue border, by default) indicating that the user has put focus on that element (e.g. by tabbing). A workaround is provided to use the :focus pseudoclass on <INPUT> and anchor elements within the wrapping semi-opaque element to manually apply a style indicating the user has focused on the element. Reported on 26 October 2006. Test page: http://www.mularien.com/browser_bugs/safari_link_opacity_bug.html Tested on locally-built debug build of WebKit r18401 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).

Seems like an incremental repaint issue: note how forcing a repaint (e.g. by switching to a different tab and back) makes the focus ring appear where expected.

I also think this might be a bug in Core Graphics in Tiger.

I came across this same bug on my own, except I had the opacity set directly on the input itself (something the newer Webkit allows). Any opacity less than 1 will cause the focus glow to not draw. I tested on a nightly download from 11/10/2007, build WebKit r27663 (on Tiger).

I cannot reproduce the reported issue in WebKit 39524 on Mac OS X 10.5.6.

(In reply to comment #6) > I cannot reproduce the reported issue in WebKit 39524 on Mac OS X 10.5.6. The bisect-builds script reports: Fails: r28505 Works: r28565 Resolving as fixed.

Broken in Safari 3.0. Fixed in Safari 3.1 and later.
