NavigationView tries to determine if it is behind the status bar by checking if it's at the top of the screen. If it is and there are insets, it will draw a scrim. It also tries to determine if it is under the system nav. If it is and the system nav isn't fully transparent, it will also draw a scrim.

Add a itemMaxLines attr to NavigationView and propagate it down to the internal CheckedTextView.
Also, make a slight change to design_navigation_item.xml layout to accommodate multiple lines of text. Without the layout change, the layout_height of the item is set to "?attr/listPreferredItemHeightSmall" so it can't contain an arbitrary number of lines. It can also chop lines in the middle.
To fix this, we change layout_height to "wrap_content" and add a minHeight attribute set to "?attr/listPreferredItemHeightSmall". This results in the same behavior for single line items but expands appropriately to contain items with multiple rows.
