You probably mean HTMLFormElement. HTMLFrameElement would not make much sense.

Thanks Chris, you are correct, will fix. I was doing too many things at the same time...

Generally looks OK. It’s a little sad when an HTML element class has so much of this sort of logic, but on balance I agree that this is an improvement.

I think this should be something you can write without "get()".

This is a significant change in behavior. Before, in a case like this, the code below would run. We will leave m_shouldSubmit set to true now, for example. Is this a desirable change?

Ditto.

> Source/WebCore/html/HTMLFormElement.cpp:394
> +        return;

Ditto.

What makes this change safe? Was this boolean doing anything useful before? If so, why isn’t it needed now?
