Collapsed appfinder window not resizable at window scaling 2x
Hi all,
I noticed a curious issue with `xfce4-appfinder` after migrating to a HiDPI monitor. When window scaling (Settings → Appearance → Settings) is set to 2x, starting the app finder in collapsed mode yields a very narrow and non-resizable finder window. After setting window scaling to 1x, the issue disappears and the window is resizable again. This is not contingent on the attached monitor — I can reproduce the issue on my 1080p laptop screen alone.
Window @ 1x scaling:

Window @ 2x scaling (notice missing maximize button):

`xfce4-appfinder` version: 4.16.1
