Checking off a box greys out every line under that

Testing version: Version 2.0 (10084)

What were you doing: Checking off a box in a todo list.

What feature did you use: The todo feature in the style bar.

What happened: As I check off a box, every line right under that is greyed out.

What did you expect to happen: That the text would get back to normal color, not greyed out.

Markdown lists required an empty line to be closed otherwise the following line is interpreted as part of the list element. Oddly this applies to headers too: %20%20%23%20header
