22.04 file chooser automatically resizing in snap apps

[Matthew Gallagher]

The open and save file dialog popup in Firefox or Brave enlarge themselves in approximately 1 second intervals until they take up the entire screen and do not respond correctly to input, with the window automatically reopening. It is possible to close the misbehaving app from the dock. Setting org.gtk.gtk4.Settings.FileChooser window-size to (-1, -1) only loops back to a new file chooser dialog being the correct size for the first second. Deb/apt pacakged apps like Evince don't have this issue, same for snaps using Qt (VLC). It is possible that I unplugged a docking station while a dialog was open.
