Nested scrolling works partially (as per http://b/122818889 ). Let's discuss if we need full support and if so make sure it works.

Hi!
What is 'partially' exactly?
How do I see it?
Thanks!

As of now:
- Nesting scroll views with a scroll direction perpendicular to the ViewPager2's orientation inside ViewPager2 works
- Nesting scroll views with a scroll direction parallel to the ViewPager2's orientation inside ViewPager2 does not work
- Nesting scroll views with a scroll direction perpendicular to the ViewPager2's orientation inside ViewPager2 works

Horizontal ViewPager2 not correctly working into a vertical RecyclerView
Set a setNestedScrollingEnabled to the RecyclerView into the ViewPager2 (across reflection) resolves the problem

ageevvalentin@gmail.com, could you provide a sample app? I'd like to learn more about the circumstances that cause the problem; putting a clean ViewPager2 inside a clean RecyclerView seems to work fine, so there must be other factors involved.

Added a patch for androidx-master-dev that demos a horizontal ViewPager2 inside a vertical RecyclerView.
Verified that it works correctly on a:
- Nexus 4 emulator with API 17
- Nexus 5X emulator with API 28
- Pixel 2 device with API 29
To reproduce:
- Check out the Android Jetpack source (at commit 256899f482ff85cddfb050f37550be7b5ec927ef) (see steps in [1])
- Apply the patch (`git apply 0001-Add-sample-where-a-horizontal-ViewPager2-is-nested-i.patch`)
- Build and install viewpager2's integration-tests app: `./gradlew viewpager2:integration-tests:testapp:installDebug`
- Run it
Closing the issue for now, but please reopen if you have a minimal reproduction app

Re-opening as requested by a few users. Narrowed down the focus to nested scrolling elements with the same scroll direction.
Description
Component used: Navigation Version used: 2.3.0-alpha06
When navigating to a destination with single top, the arguments could change, but the
NavBackStackEntry's arguments (because it isn't a new instance ofNavBackStackEntry) aren't updated. It also means they aren't fed through to anyOnDestinationChangedListenerinstances.I would expect that the arguments would be updated and that any listeners would get a callback (the destination wouldn't change, but the arguments would).
