Workaround layout problems with Material Design

In some contexts (e.g. BottomSheetDialogFrament), Material Design
themes will override the default of singleLine=false to true. This
causes layout problems because the forward/rewind buttons are no
longer visible with singleLine=true.

This problem can be avoided by explicitly requesting the default
value of false in our layout files.
