slider

Steps to reproduce:
1. Open attached slider.html in Safari.
2. Assuming default user preferences, press Option+Tab several times.

Expected behavior: it should be focused.
Actual behavior: it's not.

Unfortunately, this is the smallest range of revisions I can make. Does someone remember any suspicious changes at that time?

My changes for tyep=range:

r88294 r=kling [Bug 62207] [Qt] RenderThemeQt::adjustSliderThumbSize() should not refer to the parent style
r88301 r=rniwa [Bug 62195] Convert fast/forms/thumbslider-crash.html to dumpAsText
r88405 r=dglazkov [Bug 62208] Change the argument of RenderTheme::adjustSliderThumbSize(): RenderObject* -> RenderStyle*
r88415 r=dglazkov [Bug 62196] Allow drawing a slider thumb for any nodes

Some focus-related changes in the range:
http://trac.webkit.org/changeset/88418 Makes sure that document.activeElement won't be an element in shadow root.
http://trac.webkit.org/changeset/88421 A forward/backward tab traversal now visits focusable elements in a shadow root.

r88415 and r88421 are suspicious.  I'll investigate.

Actually it has focus, but has no focus appearance, doesn't it?
Keyboard operation is very slow in this test case because of a wide value range and the default step 1.

Looks like that!

Oops, no.  We can make a slider focus regardless of the setting.

Indentation looks strange here.

Can you put parentheses around the ternary operator condition for clarity? Some compilers might actually produce a warning otherwise.
