When I get this error, startDestDisplayName just gives me an arbitrary Dest Id when declaring startDest with Routes. I have to debug the source and check the route value to figure out what's wrong.

I suggest to display the route instead of this ID, by updating the startDestDisplayName logic or just displaying the route pattern somehow for easier debugging.

Marked as fixed.

Nested scrolling works partially (as per

http://b/122818889). Let's discuss if we need full support and if so make sure it works.
