Should this be gated behind IsSystemTrayMenuMaterial()?

[bruthig, 2016/11/01 21:10:54]

It shouldn't affect non-md.  The only ActionableView classes to override
OnMouseEntered()/OnMouseExited() are HoverHighlightView and
TrayPopupItemContainer, both of which call set_notify_enter_exit_on_child(true)
already.

Acknowledged.
