How can I have the cursor in an empty Editor be pre-marked?

[tashburn]

When my users click a button to change the current block type to a "block-quote", I want their cursor to be in the new block-quote and marked italic. The user can click a toolbar button to un-italicize it if they want.

I've tried change.setBlock(json) and passed the JSON for a text node with the italic mark. Doesn't work. The mark gets removed by Slate.

I've tried change.setBlock('block-quote').addMark('italic'). Doesn't work either. The user-entered text is not italic.

How can I do this?

As of #3093 (which was just merged), I believe this issue is no longer applicable, because a lot has changed. I'm going through and closing out any potential issues that are not out of date with the overhaul. Thanks for understanding.
