Fix stack overflow triggered by HTML file with deep <div> nesting
https://bugs.webkit.org/show_bug.cgi?id=295722
rdar://152959431
Reviewed by Ryosuke Niwa.
Pop off the HTMLElementStack when we reach max depth to accurately reflect DOM
Tree state and mimic current DOM Tree behavior.
New test makes sure that page successfuly loads given large amount of nested
divs. The bug previously would cause page to hang.
