Lexical version: v0.12.0

Steps To Reproduce

1. Create code block at end of a line
2. Try to exit with right arrow, clicking to the right of the block, Enter, or other key entries/inputs

The current behavior

Cannot exit a code block without use of the formatting toolbar

The expected behavior

Most editors allow a right arrow or a click outside (to the leading edge/cursor side) of the code block to 'exit' it and go back to unformatted text. In effect, you're 'stuck' in the code block.

I've submitted this as a bug as it seems like unexpected behavior, but I could see it as a feature request as well.
