When someone recently implemented GraphicsContext::drawFocusRing(const Color& color) in GraphicsContextCairo, text entry widgets started getting blue focus rings.
The correct fix should probably not involve any modification to GraphicsContextCairo.
I think that has been fixed indirectly by http://bugs.webkit.org/show_bug.cgi?id=15722.
I cannot reproduce this, probably as Jan says it was fixed. Alp: if it's fixed can you close the bug?
I am assuming this is fixed, and thus closing.
