Cursor Tab Accept Next Word Of Inline Suggestion does not work

Issue

Partially accepting inline suggestion works for next word, but not for next line.

I set my shortcuts as specified in the screenshots. Both are unique, regarding commands, meaning that no other commands are triggered by them. I use a Mac (German keyboard though) and am aware that this character ‘„’ is also printed by option+^. However, I tried to bind other shortcuts to accepting next line that are truly unique, but none worked so far. Furthermore option+^ does work for accepting next word. I enabled partial accepts.

I work on a MacBook Pro M3 Sonoma 14.3.1.
