Resizing panel resizes window

[hfiguiere]

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Darktable 5.2.1 from Flathub
Stock GNOME 48 on Fedora Silverblue (it's gnome-shell + mutter + Xwayland)

If I resize the side panel the window that is maximised is resized at the same time.

Steps to reproduce

Each of the videos is done after restarting Darktable and making sure the window is maximised.

Right panel

Screencast.From.2025-08-19.19-31-26.webm

Left panel

Screencast.From.2025-08-19.19-52-02.webm

After that, impossible to maximise. Minimise bring a weird size. Quit Darktable and then you can maximise again.

Expected behavior

It just resize the panels, Not the window

A note that I see this even when the window is not maximized.

Steps to reproduce:

1. Open darktable in lighttable view
2. Drag left on right panel resize area
3. Panel will expand as expected for a bit, while window size stays the same
4. As keep dragging to left, window size will increase to right as right panel size also increases

To add to the original report, it still happen in 5.4.1 using wayland natively. And the above comment matches my observation.

Will be fixed with #20610
