SUMMARY


STEPS TO REPRODUCE
0. maximize firefox/chromium on smaller resolution display
1. watch Video on YouTube double-click video to fullscreen (chromium, firefox both wayland)
2. press Meta+Shift+Left/Right to move window to higher resolution display 
3. double-click on Video again

OBSERVED RESULT
window decoration claims window is maximized
window does not fill all the available space (I assume the window is 1920x1080 big because I moved it from a 1080p Display)

EXPECTED RESULT
window fills the entire space of the bigger display
