I did a very rudimentary test and saw that Firefox and Chrome treat
links with a nested button differently.
* Firefox does not expose a link at all
* Chrome half-exposes a link (Jaws announces the link in browse mode
but not when you open a list of links)
Neither browser exposed the presence of a link nested in a button.
I'll do more comprehensive testing when I have time and throw the
example code up on CodePen or similar.
