If you navigate with popUpTo popping multiple entries off of the back stack when using Navigation with fragments, after you do another navigate and attempt to pop the stack using system back, system back does not work.

The reason for this is that if a fragment on the back stack is destroyed while it is still created, we ensure the entry makes it to destroyed, but failed to clear some associated state. The state remains around and prevents us from popping the Nav back stack during system back.
