Monitor attributes on Windows 11/WSL2

Hi all,

an AUCTeX user on Windows 11, WSL2, Ubuntu 22.04.5 LTS reported here[1]
that the function `frame-monitor-attributes' returns this (line breaks
added for legibility):

  ((name . "rdp")
   (geometry 0 108 2560 1440)
   (workarea 0 108 2560 1440)
   (mm-size 0 0)
   (scale-factor . 1.0)
   (frames #<frame *scratch* - GNU Emacs ...>)
   (source . "Gdk"))

Note the mm-size values which break the functionality of AUCTeX preview.
I can fix this in AUCTeX sources to deal with the 0 values, but is this
the expected behavior?  I don't use Windows/WSL2 so I can't test this
myself.  I suspect "rdp" means Remote Desktop Protocol.  TIA.

Best, Arash
