When a player changes their active quickbar row manually, whether it's from Shift + #, clicking on the button, using previous/next hotkeys, or rotating quickbars, none of it is reflected in the API. The script isn't ever aware of what the active quickbar is, unless the script sets the active quickbar itself.

Upon further inspection, it's because I had the quick_bar_set_selected_page permission disabled.
I would expect this permission to actually disable the player's ability to do that, rather than just make it desync state between the api and the client.

Thanks for the report. I am going to move this to Wont fix. Permissions system was implemented in a least intrusive way and so gui is not aware that input actions it is trying to send are being ignored.
