Subject: [PATCH] excmds.ts: Fix scrollto(0/100,y) not working on some websites

According to
https://drafts.csswg.org/cssom-view/#dom-document-scrollingelement
scrollingElement can be null. This happened on
http://www.angelfire.com/super/badwebs/ . This caused `elem` to be null
and resulted in an error when pressing G/gg.
