I think you forgot to upload the code for this function :^)

Also, I would make this a separate patch, and say that you used find-and-replace
to make the change :)

Took a look at this. The code for hasLayoutObject is meant to be in Bugs' patch.
CodeReview sees it as landed and is hence running my code on master - which
doesn't have the code change I need since the CL got reverted. The only way I
see of overriding this setting the dependant patch to be a copy CL of Bugs'
code. And then changing that once Bugs' patch is landed.
