Scrollbar not in sync with scrolltop

Summary Scrollbar not in sync with scrolltop

If a scrolled elements overflow is set to "hidden" and then back to "auto" with javascript, the reappearing scrollbars are not in sync with the actual scrolltop value. Test case is in the url field. The use case may seem to be quite rare, but it pops up easily when building a workaround for #21462. I found the bug when resolving issue found in Vaadin just two weeks ago (http://dev.vaadin.com/ticket/3039). I'm not 100% sure, but I suspect this to be a regression, since we have not found this earlier with Vaadin(IT Mill Toolkit previously).

The scenario on the reduced test case above works in both Safari ToT and mini-browser (gtk). Marking as fixed. Please reopen with reproducible steps, if it is still reproducible for you.
