[BUG] Window Switcher popup does not work (`JS ERROR: TypeError: box.add is not a function`)

[mkalinski]

Describe the bug After an upgrade from Gnome 45 to Gnome 46, window switcher popup stopped working.

To Reproduce Steps to reproduce the behavior:

1. Enable the extension
2. Press Alt+Tab
3. Nothing happens, application window is not switched, no popup appears

Expected behavior Active window should be switched to another one, or if Alt+Tab is held down for a moment, a window switcher popup should appear.

Desktop (please complete the following information):

• OS: Fedora 40
• Version of the extension: 46.1
• Source of installation: extension.gnome.org

Additional context Every time I press Alt+Tab, the following appears in logs:

I'm getting the same experience, and having found the command to debug it, can confirm it is the same issue. Debug command: sudo journalctl /usr/bin/gnome-shell

Thanks! It only occurred when the Show Hotkeys F1-F12 for Direct Activation option was enabled.
