* Revert "Revert "Switch comments/chat to rich text editor (#703)""
This reverts commit 33906adfe4.
* Fix typing after being weird on Android
Issue: character from mention gets deleted. Most weird on Swiftkey:
mention gets duplicated instead of deleting.
See https://github.com/ProseMirror/prosemirror/issues/565https://bugs.chromium.org/p/chromium/issues/detail?id=612446
The keyboard still closes unexpectedly when you delete :(
