To Reproduce
Steps to reproduce the behavior:
First it will put the readmore inside a wrapping <p> tag and when switching between Code and Editor View it will "fix" the error by closing the tags with a   inside that would add extra whitespace later.
Both will result in the output to be what the user wanted. We noticed it just because a customer of us has broken his page multiple times because of this.
Expected behavior
The Readmore insert should close the other tags.
