the playlist control entirely redefines key processing (arrows, enter, ...).
Yet, for keys not processed, forwarding them to vlc core is desirable.
For instance, that enables n(ext) and p(revious) when focus is on the playlist,
which is something users can expect to be working.

This was leading to a crash when using --no-keyboard-events
