This issue is NOT fixed in 44.1-1ubuntu1. I don't know whether that's because the fix from upstream didn't get included in that package somehow, or whether the upstream bug is not actually the root cause of the issue reported here. If I launch an emacs window with the new version of mutter in mantic, clicking on the title bar still doesn't raise the window, whereas clicking on the title bar of a terminal window DOES raise it. I.e., the problem I initially reported above still exists.
