For reviewers: Reasoning around implementing the show/hide via HOC logic is that we will be extending our widgets with additional features later.(i.e hover state, right click mini menu etc)

Just a nit to say that this (and some other things in this PR) breaks backwards compatibility with the brave-core consumer, so any gap between this PR being merged with brave-ui's sha that brave-core is using, and the sister brave-core PR being merged, will result in broken builds. But the remedy for now is just to make sure they are merged very quickly together :-)
