Undoing list block creation causes loss of keyboard focus

[brianhogg]

Describe the bug
If you type - (dash) then space, the paragraph block converts into a list item block. But if you then Cmd+Z to undo (ie. you just want a dash not a special bullet block) you lose keyboard focus and have to mouse into the block.

To Reproduce
Steps to reproduce the behavior:

1. Create a new paragraph block
2. Type - then a space
3. Press Cmd+Z (OSX)
4. See keyboard focus is lost and you can no longer type in the reverted paragraph block

Expected behavior
Keyboard cursor remains in the paragraph block

Desktop (please complete the following information):

• OS: MacOSX 10.13.6
• Browser: Chrome
• Version 70.0.3538.110 (Official Build) (64-bit)

Hi @brianhogg, @designsimply thank you for reporting and testing this issue. I think this is a general RichText problem of focus not being managed and is covered in #9740. I'm going to close this issue for now so we can converge in the other issue which is more general.
