** Description changed:

  Impact
  ------
  There is a new point release in the stable GTK 4.6 series.
  
  https://gitlab.gnome.org/GNOME/gtk/-/blob/4.6.3/NEWS
  
  Also, we are cherry-picking a few patches
  - Work around infinite loop in box allocation (Closes: #1010547)
  - Make it easier to select the current folder with a file chooser
  - Fix saving into a subdirectory with a file chooser
  - Fix text view scrolling with mutter 42.1 (LP: #1972722)
  - Fix an invalid format string with EGL support (fixes an issue for a 
Canonical customer)
  
  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
  snap run portal-test
  Verify that the app seems to still work ok
  
  What Could Go Wrong
  -------------------
  Ubuntu includes xdg-desktop-portal-gnome by default which is used for many 
snap actions like providing a file chooser. 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 it's not affected by this SRU.
  
  The other gtk4 apps installed by default in Ubuntu are gnome-chess and
  gnome-shell-extension-prefs.
  
  gtk is not listed in the proposed set of packages at
  https://wiki.ubuntu.com/StableReleaseUpdates/GNOME
  but I believe it should be.
  
  gtk4 has extensive build tests and autopkgtests.
  
  Other Info
  ----------
- The invalid format string patch has been cherry-picked to the Debian Salsa 
branch and will be included in the next kinetic upload.
- 
  This upload also includes some build test workarounds applied in Debian for 
https://gitlab.gnome.org/GNOME/gtk/-/issues/4889
  Some tests provided by GTK (and pango and librsvg) are not flexible enough to 
be used when dependency versions are not exactly the same as in the upstream 
developer's system
