If text is in the filter of the token bag and FG loses and regains focus, the token bag loses its arranged setting.

Recreation:
1. Have a campaign with tokens that are arranged.
2. Type text into the filter field of the token bag.
3. Switch from FG to another program.
4. Switch back to FG.
5. Middle-mouse-button-click to clear the filter

The tokens suddenly scramble instead of retaining the arrangement.
