When a window is switched to be FullScreen then it will end up keeping a bar at the bottom of the window which should not be visible

When the QML Windows visibility is set to FullScreen, the space reserved for bottom navigation bar remains visible and the window is not resized to full extent.

Note that it works if the visibility is set initially to FullScreen. The issue happens when visibility is toggled.

QTBUG-94990 describes similar case, but not sure if it is related the root cause of this bug.
