The following line is the culprit (578 of wp-includes/js/tinymce/plugins/wordpress/editor_plugin.js):

pee = pee.replace(new RegExp('\n*([^\Z]+?)\\n{2}', 'mg'), "<p>$1</p>\n");

I don't know how to fix it, because I don't have a clue what that line is supposed to do.

That line

That line is meant to grab everything up to a double line ending and put it in a paragraph. Backslash-Z should mean "all characters not being the end boundary of a line." I'll work out a better pattern.
