  [ Test Plan ]

  Test Case 0
  -----------
  gtk4 has an extensive build test suite, and failures will fail the build.
  gtk4 also has thorough autopkgtests.
  Ensure that the build succeeds and that the autopgktests pass.

  Test Case 1
  -----------
  Make sure that opening and saving files from the Firefox and Chromium snaps still work

  Test Case 2
  -----------
  snap install portal-test --edge
  snap run portal-test
  Verify that the app seems to still work ok

  Test Case 3
  -----------
  Install and test gtk4-demo (from the gtk-4-examples package) as well as a few other GTK/GNOME applications like nautilus and gnome-text-editor, and verify that they continue to launch and work as expected.

  [ What Could Go Wrong ]

  Many of the default Ubuntu desktop apps use GTK4. A serious enough
  regression could severely break the Ubuntu Desktop.

  Ubuntu includes xdg-desktop-portal-gnome by default which is used for
  many snap actions like providing a file chooser using GTK4. This is
  critical functionality for our snaps. The Ubuntu flavors use a
  different portal backend, most commonly xdg-desktop-portal-gtk which
  uses GTK3, so are not affected by this SRU.

  [ Other info ]

  gtk4 is included in the GNOME micro release exception.
