Breeze theme not applied

SUMMARY
QtWidget applications don't seem to be getting themed with Breeze on Neon Unstable. This has been happening for over a month, but I thought my install was just broken. Today (ISO from sept. 30th) I tested a brand-new ISO and I'm still seeing it. I'm unsure if this is Neon-specific, but since I didn't see anyone complaining about it I guess it must be missing some package.

STEPS TO REPRODUCE
1. Open Dolphin in a Neon Unstable session

OBSERVED RESULT
Breeze is not applied to QT Widget apps

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.27.80
KDE Frameworks Version: 5.240.0
Qt Version: 6.6.0

This only affects QT5 applications on a Plasma 6 session. The package Breeze5 is installed.
Comment 2 Quinten Kock 2023-10-02 21:07:45 UTC
A workaround is to run

sudo apt install kde-style-breeze5

This should probably be included in some kind of base package.
