There are situations due to browser quirks or Bootstrap CSS where
an anchor tag is needed, when semantically a button tag is the
better choice. SafeAnchor ensures that when an anchor is used like a
button its accessible. It also emulates input `disabled` behavior for
links, which is usually desirable for Buttons, NavItems, MenuItems, etc.
