Bring up an editor window (e.g. apprunner -editor). Click in a non-preformatted text block in the lower part of the page. Type a space. Watch it scroll down so that the insert position is now at the top of the screen. Major usability problem for the editor. I first saw this in the 4/12 build; didn't see it in the builds from the middle of the previous week. Mjudge thinks this is happening because the event system isn't noticing that the space was already handled, so it's activating its scrolling routine. May be related to bugs 4973 and/or 3999.

Changing target to M5 (was M4!) so it will show up in M5 queries.

This is a dupe of 3999. Spacebars causing a scrolldown. I have most of a fix on my machine in Mountain View (out of town now). Will try to finish fix and get in asap when back. *** This bug has been marked as a duplicate of 3999 ***
