I can confirm the fix helped. I verified it according to the steps in this bug (bug 1845302) and also according to the steps in bug 1850046 (its gnome-shell's part).
BTW when I run "killall -CONT firefox" (see the original description in this issue), the app is closed. I guess it's correct behavior because in the previous step I chosen "Quit" in the context menu of the app. If I don't choose "Quit", "killall -CONT firefox" continues running of the app as expected.
