implement mouse back button functionality

Hello there, first of all, graphiql is the best graphql explorer and query editor for me, I always prefer graphiql over other tools :)

When I click on query and go deep into a type and want to go back, back button from mouse doesn't actually work, and I've to click back button on top, it'd be nice to implement back button functionality on that docs frame, that'd make it much easier to navigate there,

it doesn't look like a lot of work, it seems like just a mouse handler and performing a back operation, any ideas?
