Potential bug in Image mode on Emacs 29 PGTK on Wayland

[Soham Gumaste <sohamg2@gmail.com>]

Hello,

I think I have come across a potential bug -- On emacs 29 PGTK, .ppm
files dont render `image-toggle-display` is called. I was just
experimenting with different versions of emacs, and the non-pgtk build
for emacs29 does NOT have this issue.

Steps to repro:
0. Use emacs 29 PGTK on a Wayland desktop environment
1. C-x C-f a file that is of the .ppm format (Portable Pixmap Format)
2. C-c C-c to view the image
3. Nothing happens.

I can, however, "fix" this "bug" by setting
`inhibit-eval-elisp-during-redisplay` to `t`, but that also breaks a
bunch of other stuff. Please let me know how I can document this
further, or if it is an issue on my end.

My configs are as follows:
Emacs config: https://github.com/SohamG/dotfiles/blob/main/.emacs.d/configuration.org
Emacs package: `emacs29-pgtk` as found in NixPkgs 23.11

Please include me as To: and/or Cc: as I consume this mailing list via
the digests option of mailman.

Thanks
