Steps to reproduce the issue:
- Have multiple saved windows
- Create a throwaway saved window
- Make your sidebar narrow enough that the icons of the inactive saved windows aren't shown:

- Delete the recently created saved window
- Some of the saved window icons are now invisible but they can still be clicked on
- Hide the sidebar and open it again → the icons are back to normal

Expected behavior:
The saved window icons should not break even though they see other saved windows disappear.
