STEPS TO REPRODUCE 1. In Plasma 5, move your panel to the left screen edge, make it centered, put it in "Windows can cover" mode and give it custom min and max heights. 2. Upgrade to Plasma 6 OBSERVED RESULT The panel is still on the left screen edge (good), still centered (good), has changed from "Windows Can Cover" mode which was removed to "Dodge Windows" mode (good). However it has become vertically maximized rather than retaining its custom dimensions (bad). The height mode is set to "Fill height" instead of "Custom" as it should have been. EXPECTED RESULT Height mode set top custom, and prior minimum and maximum heights should have been preserved from their Plasma 5 values. ADDITIONAL INFORMATION This was tested in a KDE Neon VM, going from Neon User to Neon Unstable by changing the repos and upgrading.
