The :hover state for outline buttons is effectively the same as the :active state, so it can be difficult to tell the difference between a button that is hovered over and one that is active - particularly when using eg checkbox/radio buttons as buttons, which uses the active class to show that something is selected.
This change adds $hover-background and $hover-border as options to the button-outline-variant mixin, and gives them default values half-way between than the $color and white.
I think this is related to #26804 (closed)
