Error with ExpandableListView in Theme.AppCompat.Dialog theme?

Question

Android

Good afternoon.
In a window that has Theme.AppCompat.Dialog theme, I make a tree-like list ExpandableListView .
The list itself with the necessary groups and values ​​is formed without problems. A collapsed list of groups is shown and clicking on a group to expand it throws a java.lang.NullPointerException: Attempt to invoke virtual method 'void android.graphics.drawable.Drawable.setBounds(android.graphics.Rect)' on a null object reference.
Please advise how to fix this error.
Ps if you change the theme of the activity, for example, to Base.Theme.AppCompat.Light.DarkActionBar, then the list expands without problems.
