Depiction of the problem.

SUMMARY
VLC's *unstylized Qt* tooltips are rendered with the default KDE Plasma 6 font, instead of the font (the `monospace` `fc-alias`) which I've chosen.

STEPS TO REPRODUCE
1.  Install https://download.fedoraproject.org/pub/fedora/linux/releases/test/40_Beta/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-40_Beta-1.10.iso
2.  Apply https://code.videolan.org/videolan/vlc/uploads/1137ae2d7256543ffff2a6e2ac79c085/Screenshot_20240422_000602.png as the configuration of `kcm_fonts`.
3.  Launch https://download.fedoraproject.org/pub/fedora/linux/releases/test/40_Beta/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-40_Beta-1.10.iso

OBSERVED RESULT
VLC's tooltips are rendered with the default KDE Plasma 6 font, instead of the font which I've chosen.

EXPECTED RESULT
The tooltips should definitely be rendered with my chosen font.

I don't know whether this is a bug on KDE or Qt's end, but I'm informed that it shouldn't be on VLC's, at least.
