trying to force window rules

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.

STEPS TO REPRODUCE
1. Log in on Wayland
2. Open Gwenview
3. 

OBSERVED RESULT
Gwenview opens, for a split second at the right size, but then the windows resizes itself increasing height. This hides the bottom part of the interface outside of the screen view. On a X11 session I can use Window Rules to force a maximum size of the window, but on Wayland this Plasma Feature does not work.

EXPECTED RESULT
Gwenview open and stays at the right size.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: NEON USER
(available in About System)
KDE Plasma Version: 5.27.0
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8

ADDITIONAL INFORMATION
This problem doesn't affect Gwenview only, other programas are also affected. Qbittorent, Pinta too for example, curiously "QT" programs. This started happening sometime during the second semester but I can't say for sure for how long this problem with Windows Rules not working on Wayland is on Plasma because for me is still impossible to use Wayland, too many problems.

If I find other Plasma programs with this issue I'll report.
My resolution is 1366x768.
