[EditContext] Issues for May 11 meeting

[dandclark]

I wanted to tag a couple of EditContext issues here to make sure they make it on the Agenda for the Thursday May 11 meeting:

• Should it be required to call updateCharacterBounds() synchronously in the characterboundsupdate event handler? edit-context#36 Should it be required to call updateCharacterBounds() synchronously in the characterboundsupdate event handler?
• EditContext: supported element list seems somewhat arbitrary edit-context#19 EditContext: supported element list seems somewhat arbitrary

Hey @dandclark as you can see in the README.md of this repo, we automatically pick up the items tagged with Agenda+ in the edit-context repo, so it's not required to tag them here a second time.
