I'm getting an wrong behavior when showing an Bottom Sheet Dialog in landscape mode. The problem occurs in the 24.+ version of the design library. According below image the Bottom Sheet is not showing correctly only in landscape. Im using BottomSheetDialog class and i'm following this tutorial: http://www.skholingua.com/blog/bottom-sheet-android, in my published apps the problem also occurs.
I tested the 25.+ version and the problem was not solved.
Error In landscape 24, 25.+ Library
Same example in 23.+ Library
