Apparently dialog fragments do not change the state of the fragment it
is overlaid on, resulting in it still having active StateFlow
collectors that will intercept new playlist requests before
AddToPlaylistDialog. Once again sharing StateFlows across views has
bit me.
In the future I may try to preserve the navigation idioms by not
stacking NewPlaylistDialog on AddToPlaylistDialog and instead
simply swap them out. I think this would also be better design too
(It's not like I'm allowing other decision dialogs to be exitable
back to their prior dialog).
