Bug ID: 461840
Summary: When opening a file, window resizes and re-positions
itself after launch, which looks bad on Wayland
because re-positioning isn't supported

Screen recording
See attached screen recording on Wayland.
When opening a file in DragonPlayer, its main window briefly appears according
to the configured window placement mode, and then it loads the file. When it
does this, its window may become larger to accommodate it, if it's a video
file.
On X11 the window also re-positions itself to preserve the appearance of
growing in all dimensions, which presents no problems other than a brief
flicker on launch.
But on Wayland, windows can only resize themselves and not re-position
themselves, so the window grows from its top-left corner. This causes the
window to be positioned oddly, and its bottom and right edges can get cut off.
It would be ideal if the window opened at the correct size immediately so that
KWin's window positioning code can position it properly, rather than opening at
one size and then resizing and re-positioning itself later.
