Bug 51632 – Pass style for <area> instead of associated <img> when querying whether the theme draws the focus ring for an <area>

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Daniel Bates]

We should pass the style of the focused <area> to RenderTheme::supportsFocusRing() to determine whether theme is responsible for painting focus rings for <area>s. Currently, we pass the style of the <img> associated with the focused <area>.

Patch

It's not possible to test this at this time since there are no themes that override focus ring drawing for <area>s.

I spoke with Eric Seidel on IRC on 12/28/10 about this:

[3:22pm] dydz: eseidel: hi. With regards to <https://bugs.webkit.org/show_bug.cgi?id=51632> I thought to make this change for correctness
[3:23pm] dydz: Although, you're right the move does not have any impact at this time
[3:23pm] dydz: Maybe it is sufficient to just keep the bug around to remember to move this should someone what to detect <area>s
[3:24pm] dydz: *want to detect <area>s and do custom focus ring drawing
[3:25pm] dydz: Notice, <img>s do not have a concept of a focus ring since they are not focusable. It is the <area> element this is focusable.
[3:28pm] dydz: eseidel: That being said, would you suggest we don't make this change at this time?
[3:29pm] eseidel: dydz: I'm just not sure what it's doing or why 
[3:31pm] dydz: eseidel: It's a semantic change based on the idea that when drawing a focus ring for an image map we are really drawing a focus ring for an <area> not an <img> (see <http://www.w3.org/TR/html5/the-map-element.html#the-area-element>)
[3:32pm] eseidel: dydz: ok.  so I would just leave it up for review and forget about ti.  eventually hyatt or someone will look
