Bug 89280 – REGRESSION (r120246): <video> progress control doesn't draw handle on Mac

• Component: Media
• Status: RESOLVED FIXED

[Tim Horton]

See attached screenshots. The little grabby handle on <video> on Mac broke in http://trac.webkit.org/changeset/120246. Possible that we should have investigated instead of rebaselining the tests, unfortunate that we don't have pixel tests in a good state.

Can you check if the volume thumb is still there?

It may be related to the change of media slider thumbs to a shadowPseudoId of "webkit-media-slider-thumb" from "webkit-slider-thumb".

The volume thumb is also missing.

OK, since my build doesn't replicate the bug, could you check whether changing this rule in WebCor/css/html.cc to add  "input[type="range"]::-webkit-media-slider-thumb" might fix it?

input[type="range"]::-webkit-slider-thumb {
    -webkit-appearance: sliderthumb-horizontal;
    -webkit-box-sizing: border-box;
    display: block;
    position: relative;
}

[Silvia Pfeiffer]

If that works, also add input[type="range"]::-webkit-media-slider-container to the rule of input[type="range"]::-webkit-slider-container .

Works great, will you land it? I'm not 100% sure what I'm changing, so it's hard to write a changelog, nor am I sure that was the final goal versus just a test.

Can do. Give me an hour or so.

Looks like this cause media/controls-after-reload.html to fail:

Probably the rebaseline in http://trac.webkit.org/changeset/120345 was wrong.

[Silvia Pfeiffer]

If the controls look ok, yes, I would assume the rebaseline should be redone.
