Can't install aseprite extension by double clicking when preferences are open

so i was trying to do some aseprite extension(which are surprisenly easy perks for the coder) and i noticed that when i have the preference window open i cannot install any type of extension by double clicking on the extension file, be it palette or theme extensions, is not a major problem since i can just close preferences and double click it to work, and i thought i might report it.

Aseprite windows, steam version 1.2.25
