All of the context and investigation is in ENG-3954, but encompassing ModalOverlay in a focus-trap
was blocking all tooltip actions, since it was not contained within the trapped DOM element.

There were a few solutions proposed, this one is just the simplest. There are two configurable options that can be passed into the component,
clickOutsideDeactivates and allowOutsideClick. Both seem to resolve the issue, but I opted for allowOutsideClick as instead of entirely deactivating the focus-trap and letting outside clicks to continue, it
just filters through the click and allows outside actions.
