Checklist
Changes proposed in this pull request:
Currently if the target is focused and the popover is meant to open on click, then you cannot open the popover via keyboard-only navigation.
This change makes it at least so that pressing enter while the target is focused the popover will open. Note that the popover currently always steals focus away from the target, so that you cannot press enter again in the same way that you could click the target again to close the popover. I'm not sure what was intended behavior (stealing focus) or not, so I could use advice as to how would we allow focus to remain on the target such that 2 enter key presses opens and then closes the popover
Reviewers should focus on:
Any other gotchas with adding this event listener?
