Error marker rendered on top of text on mobile

Just to clarify, do you mean the "parser stopped here" marker on line 3, or the red bar next to "example"?

I intentionally made the "Parser stopped here" not take up as much space because it was pushing the content around before, but that decision may need more refinement.

The red bar on the left should definitely not touch the text.
