Cameron, Boris: could you take a look at this assertion failure, thanks!

Comment 2

[Boris Zbarsky [:bzbarsky]]

So this is asserting for an <a> whose parent is a <span> whose parent is a <div> whose parent is a <map>.

The primary frame of the <a> is an nsImageFrame.

So this is fundamentally the same as the <area> case.

We could loosen up the assertion to also allow <a> elements, I guess, or <a> elements that are descendants of <map>....

Or just stop supporting <a> as special inside <map> as in bug 1317937.
