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

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.

Any progress on this? (only talking about the "same scroll direction" issue)
I searched a lot for workarounds on Google and SO, but it seems no one really found a suitable solution yet.
The thing is that all other VerticalViewPagers out there have other problems that are similarly annoying. Most of them revolve around touch issues like "What's a click and what's a swipe" or "what's the fling threshold to snap to the next page".
So if someone knows of a working sample of VerticalViewPagers, I'd be happy to see a link :)

Description
Version used: navigation-fragment-ktx, navigation-ui-ktx 2.6.0
Devices/Android versions reproduced on: All
If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue in the following github link:
When I open an app by the deep-link and back-pressing, it crashes. Also, bottom navigation tab 2 has dynamic fragment logic. It will change fragments when the API has a data response. (A sample project doesn't use the API.)

Please use the navigate() function to add fragments to the FragmentNavigator managed FragmentManager.

Issue does not occur when downgrade version 2.6.0 to 2.5.3 or normal open an app
Steps to reproduce
1. run script deeplink (file name test_deeplink.sh in a project)
2. press back system
3. App crashes with the above error
