Does anybody know whether or not it will be possible to use the GTK3.2's new HTML5-extension in Ubuntu 12.04? They announced that GNOME3.2 will be included, but will they build the GTK packages with the new HTML5-extension enabled? Unfortunately thy did not in 11.10.
Well, apparently not:
You could try to create a bugreport for the Ubuntu GTK3 package, asking to compile it with --enable-broadway-backend
