Consider merging https://chromium.googlesource.com/chromium/blink/+/53ff5c99564ef1677df4f3575a206d32557e0eaa We should always use lazyAttach instead of manually causing reattaches. reattachIfAttached is bad because it encourages manual reattaching instead of letting the next style recalc handle it for you which can result in bad performance. For example setting and unsetting the open attribute on <dialog> elements causes the synchronous destruction and recreation of the entire renderer subtree repeatedly. This change makes sure that we defer all that work until the next style recalc.

Also https://chromium.googlesource.com/chromium/blink/+/d5b57e33ccbf9a89912773d1b12374fbc7f715f8 HTMLSelectElement should use lazyReattach When changing the size attribute on <select> we shouldn't do a sync reattach().

lazyAttach is not something in Webkit. So marking this as "RESOLVED WONTFIX".
