Describe the bug

Good example of proper accessibility for modal.

I met with Gen Herres to review accessibility of new blocks. Two improvements can be made to the Modal block that we discovered.

• After clicking escape, close, or clicking outside the modal which closes it, focus should return to the button that original opened the modal. Right now, focus is lost.
• After clicking "Attending," the modal does not close (which is correct), however, focus should be on "Close" as that's the next logical step (if close button exists).
