typo: casese

Every time I see this pattern it bothers me. I want it to be "return adoptRef(new HTMLAudioElement(tagName, document));"

I guess the default value for HTMLFormElement* was never used.

Consider adding "inline" here, since the constructor is only called from one place.

Add "inline"?

That small c and comma after 2009 are non-uniform. If you wish, it is fine with me if you change that to "(C) 2009 Google..." in any of these files.

Thanks, I'll fix that.

That's the underlying purpose of this sequence of patches. Once every caller is using create functions and the calls to new are all in a smaller number of call sites, then we can change the reference counts to start at 1 and we will then use adoptRef. It's safer for me to separate the "make a create" function step from the "change reference counts to start at 1" case.

Yes, true.

OK, I'll think about it for those.

OK, I might do that.

I meant:

It's safer for me to separate the "make a create function" step from the "change reference count to start at 1 and use adoptRef" step.
