Find in edit mode transposes typed numbers to letters

1. Edit a page in confluence
2. Make sure Num Lock is on
3. Press CTRL+F and quickly type in numbers from the NUM pad (ie, pretend you are searching for a number 1234)
4. Notice that "1234" gets transposed to "abcd" in the Find box.
5. Notice if you wait for the animated "Find in page" dropdown to complete before typing, the numbers will show up correctly. Also, this doesn't affect numbers typed into the number row on the keyboard, only affects the Number pad (numpad).

This isn't a problem with the browser's built-in find, it is a problem with the overridden find that appears when editing a page.

Tested in multiple browsers (Fiefox, Opera 28, IE 11)
