How to use ViewPager inside RecyclerView items?

Question

Android

How can I get the ViewPager to work correctly in the RecyclerView elements of the ViewPager list? Created a small test application to demonstrate the problem:

In the screenshot RecyclerView + LinearManager with absolutely identical (in theory) elements in the amount of 5 pieces. However, only the first element works correctly (shows fragments inside the ViewPager). Each element contains only ViewPager. I set the background color of the ViewPager itself to red. It has a FragmentPagerAdapter connected to it that creates blue background fragments.

Whole project: ViewPagerInsideRecyclerView.zip
Already spent quite a lot of time trying to understand what is happening, but so far to no avail. Anyone met with something like this? What are the options for solving the problem?
UPD:
If you do not set the PagerAdapter to the first element in the onBindViewHolder method of the RecyclerView adapter, then all list elements will be red:

@Override
public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) {
    FragmentManager fragmentManager = ((AppCompatActivity) mContext).getSupportFragmentManager();
    if (position == 0) return;
    holder.viewPager.setAdapter(new MyPagerAdapter(fragmentManager));
}

After long painful dances with a tambourine, I finally managed to find a solution. In the onBindViewHolder method of the RecyclerView adapter, you need to assign a unique ID to the ViewPager. I did this:
The internal magic of Android only understands that the pagers in each element of the list are different.
