I don't think this makes sense.

We should modify InsertLineBreakCommand and/or InsertParagraphSeparator to break out of the pasted content instead.

I don't think we want to restrict this behavior to just this case mode.
It'll be also fragile because then we won't be testing this code path as much.

Nit: whitespace.

Nit: Use = instead of copy constructor syntax.

We should look for the root editable element instead as we talked about the other day.

Use createDefaultParagraphElement instead.

A better condition to check would be misleadingly named isStartOfDocument and isEndOfDocument.

I should move this out of the parent class and into the base class

This has been fixed a different way.
