Steps to reproduce:
Open Orion with a new window (unnamed). Open a second new window (automatically named "window 2"). Close this window. Original window now has long window switcher icon taking up most of toolbar (see first screenshot). Additionally, I have not found a way to return the icon to original size. Closing Orion, or removing and adding the window switcher back to the toolbar does not return it to original size (see second screenshot). Only naming the window, or opening a second window again, returns it to a reasonable size.
Closing second window should revert back to no icon or small window switcher icon.
