Enable mnemonics seems to break Alt+x shortcuts
I upgraded recently to 3.32 and my Alt+N shortcuts for changing tabs stopped working, instead delivering actual Alt+N keypresses to the running task. I tracked it down to the "Enable mnemonics" setting in General - with this turned on then Alt+N keypresses seem to bypass being handled for shortcuts. With them disabled, the Alt+N keypresses are routed to switch tabs as configured. (GtkK 3.24.8 if that is relevant.)
