Issue: Expansion tile items are not scrollable which causing error in landscape mode.
Labels: framework,f: material design,has reproducible steps,P2,found in release: 3.3,found in release: 3.7,team-design,triaged-design

I am trying to achieve a case where the expansion tile should be fixed and the contents below the expansion tile to come in a listView, also the children of expansion tile also needs to be scrollable, so that it will work fine for both portrait mode and landscape mode.

Portrait mode because bigger screen size, tile is able open without space error.

Due to less space, tile is throwing error in landscape mode.
