Description Mark Macdonald CLA 2013-07-10 13:00:16 EDT 
1. Load the Orion editor page at zoom = 100%
2. Load a file (at least a few hundred lines) into the editor, scroll to the bottom of the file.
3. Increase the browser zoom level to 125% (Ctrl++)
4. Click on some text to move the editing caret. The hit testing is wrong.

If you scroll the editor up and down, the hit testing will eventually correct itself.

Happens in 
 Chrome 29 (dev channel)
 Firefox 23 (beta channel)
 Didn't test IE or Safari
