Steps to Reproduce:

1. Hit cmd+f to start a search and toggle on the regex button
2. Perform a search that has multiple matches
3. Hit option+enter to place multiple cursors on all matches
4. Press cmd+f again to refocus the find bar
5. Notice that the regex you types is now gone! Replaced by a match or a previous search or something.
