Do not handle open attribute removal the same as HTMLDialogElement::close()

[Tim Nguyen (:ntim)]

Right now, removing the open attribute manually is handled the same as calling HTMLDialogElement::close().

However, the spec: https://html.spec.whatwg.org/multipage/interactive-elements.html#the-dialog-element:event-close explicitly says this is wrong.

Only the close() method should switch the state to closed, unblock the document from the active modal dialog and fire the close event.

Please explain in the change log the changes to this function as they seem non-trivial.

This is not how we write FIXME comments: https://webkit.org/code-style-guidelines/#comments. Please write a proper sentence ending with a period.
