** 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
