Is the frame guaranteed to have a renderer at this point?

[kenrb, 2014/06/16 15:43:38]

I was thinking yes, but now that you ask I am not certain. The frame has to be
attached to the DOM and have been navigated, which I think means must have had
attach() called at some point, but might there possibly be race conditions if it
has its renderer later destroyed?

[ojan, 2014/06/17 16:42:11]

Yeah, I'm not sure. You could put in an ASSERT(frame()->ownerRenderer()) and see
if any layout tests or webkit_unit_tests hit it.
