[Speedgrader] Improve accuracy when highlighting student text in assignments

Problem statement:

So the number one reason I HATE grading in Canvas is that I try to highlight specific pieces of text in my students assignments so I can comment on it, and Canvas seems to have a mind of it's own. It highlights portions of the text I did NOT scroll over, usually down, and I have to erase that comment and try again. This SLOWS my productivity so, so much and makes me want to return to pen on paper.

Proposed solution:

I have no idea what's going on. If it's based on what my students cut and paste in the document or what, but it's maddening. But that's the maddening part of so much of Canvas formatting. Including when I cut and paste text into Canvas. It's terrible. WE ALL USE WORD and it doens't recognize word's tabbing and worse, we can't tab. But that's another post.
