We shouldn't use .mm for cross platform code like this. Please keep this a .cpp file and factor out the objective-c bits into their own classes.

Right, so add a Source/WebCore/Modules/model-element/HTMLModelElementCocoa.mm with these bits?

No test?

Typo provinding

Add a space between these lines.

What about if it is a .reality file?

Can you put a note in here that this is a temporary solution and we don't want to write to files?

If there isn't a renderer you probably just want to exit.

if (!this->renderer())
  return;

auto size = this->renderer()->aBB...

I didn't know you could do this! Very nice.

I usually try to add some c++ wrapper class in its own files instead to avoid having multiple implementation files for the same header which is not something that is very understandable.
