The update to Plasma 5.24.4 appears to have introduced a new minimum FullRepresentation size of just 5x5 units, which is just comically small. It previously was 18x24. The widget was fine before updating to 5.24.4.
STEPS TO REPRODUCE
1. Open the clipboard widget.
It is way too small to be of any usefulness.
It has the same size of other widgets, i.e. 18x24.
Linux: KDE neon
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.93.0
