Description of the issue

When using a VerticalGridView with a ConcatAdapter, the focus jumps when passing from an element from one sub-adapter to an element from the other sub-adapter.

E.g.:

Adapter 1 = 2 elements
Adapter 2 = 15 elements

Focus is on element 0 (Element 0 of Adapter 1)
I press the DPAD down
Focus is on element 1 (Element 1 of Adapter 1)
I press the DPAD down
Focus is on element 4 (Element 2 of Adapter 2)
I press the DPAD up
Focus is on element 3 (Element 1 of Adapter 2)
I press the DPAD up
Focus is on element 2 (Element 0 of Adapter 2)
I press the DPAD up
Focus is on element 0 (Element 0 of Adapter 1)

A recording of this can be found here: ConcatAdapter_bug_on_Android_TV.mp4.

This issue is being reported by multiple partners - do we have visibility on how widespread it is?

I looked at Pitot and can't find these errors. In fact errors reported for leanback apps seem to be pretty low.

Marked as fixed.

There a few reports, but never had a way to reproduce it.

It will be helpful if you can find a reliable way to reproduce and paste a sample app with source code.
