In Chrome, Win 8, Vector;
I'm trying to change the target for the "language variant" link at the bottom of https://www.mediawiki.org/wiki/VisualEditor#History .
Right after I select the new target, the page scrolls to the top.
This doesn't take place if you insert or alter a node (template, comment), apply/unapply a simple annotation (bold), or apply/alter the other rich annotation (language).
