Updated the bug description and title to turn this into a SRU bug.

** Description changed:

- While doing the WSL Import and run test for 24.04.2, gtk4-demo failed to
- launch due to missing the library for libGLESv2.
+ [ Impact ]
+ 
+ * libgtk-4-1 has an implicit dependency on libgles2. GTK4 apps running
+ on containers like WSL, where the installation doesn't come with all
+ required dependencies upfront, crash immediately due the missing
+ dependency.
+ 
+ * gtk4 version 4.14.5 makes that dependency explicit, so libgles2 will
+ be installed automatically when libgtk-4-1 is installed.
+ 
+ 
+ [ Test Plan ]
+ 
+  Test Case 1 - gtk4-demo on containers
+ --------------------------------------
+ * Setup an Ubuntu 24.04 container (Ubuntu on WSL instance, LXD or docker, as you wish).
+ 
+ * Make sure it doesn't contain the libgles2 package already installed
+ (`apt list --installed | grep libgles2` output should be empty)
+ 
+ * Update apt cache and install gtk-4-examples and try running gtk4-demo.
+ 
+ With previous versions of GTK4 it fails to launch due libgles2.so not
+ found. With the proposed patch libgles2 will be automatically installed
+ and gtk4-demo will just run without crashes.
+ 
+ 
+ [ Where problems could occur ]
+ 
+  * Many of the default Ubuntu desktop apps use GTK4. A serious enough
+ regression could severely break the Ubuntu Desktop.
+ 
+ 
+ [ Other Info ]
+ 
+ gtk4 is included in the GNOME micro release exception since it is part
+ of GNOME Core
+ 
+ https://documentation.ubuntu.com/sru/en/latest/reference/package-
+ specific/
+ 
+ The issue was first discovered while doing the WSL Import and run test
+ for 24.04.2 documented in the ISO tracker. gtk4-demo failed to launch
+ due to missing the library for libGLESv2 (so would any other GTK4 app
+ running on WSL or LXD containers, for example).
  
  Installing libgles2 fixed the issue.
