Description
Undo doesn't work properly after drag & drop text.

Recording

slate-bug-report.mp4

Steps
To reproduce the behavior:

Open rich text example: https://www.slatejs.org/examples/richtext
Turn the quoted text into a heading element
Select part of text in the heading element, drag and drop it into the paragraph element
Undo

Expectation
Content of the heading element should be restored.

**Actual
Content of the heading element is restored.
And the heading element is turned back to quoted text.
It looks like that undo is invoked twice.
