Description Chris McGee CLA 2013-06-20 09:09:37 EDT 
For a bit of context, I am using firefox 21 and 13/14 point font in the editor preferences. I am also using a snapshot of the Orion 3.0 code base from git from a week or two ago so perhaps this is already fixed.

When I select a medium sized block of text (~20-30 lines) and paste it somewhere else in the same editor I begin to notice my cursor going out of alignment with the insertion point and selection. For instance, I will click on a line and notice that the insertion point is placed on the line above. When I drag to select some text the selection appears to be above my cursor.

Refreshing the browser page doesn't help. The only way I know to get back to a sane state is to change the editor's font preference back and forth between 13/14 point a couple of times.

I see this in master using Firefox 22, so it does not appear to be fixed

The problem happens because Firefox is change the scrollTop of the editor clipDiv.  The fix is to reset it to 0 during the editor update.

Refresh of the page does not help because FF remembers the scroll offset.
