GTK4 filechooser gets bigger every time it is opened
After updating from old xdg-desktop-portal-gtk-1.8.0 to 1.14.0 and xdg-desktop-portal-gnome-42.1 I noticed that file chooser is now using GTK4 instead of GTK3. One side effect is that each time file chooser is opened, it gets bigger and bigger until it fills the whole screen. If I resize it manually to a small size, it gets progressively resized each time it is opened again.
Removing xdg-desktop-portal-gnome to force the system to rely on old gtk3 based xdg-desktop-portal-gtk makes the problem to stop.
I can reproduce it easily from google-chrome for example that relies on xdg-desktop-portal for the file chooser selection
Thanks for your help
