A tag beginning with an underscore mess up the live preview render. If the underscore is inside or at the end of the tag, the render will be correct. The reading mode is not affected.
Steps to reproduce
Activate live preview
Insert a tag beginning with an underscore and write some text after the tag (ex: #_todo this thing)
The tag should render the underscore and the text after the tag need to be rendered normally.
The text after the tag is rendered in italics and the underscore of the tag disappear.
