I am an instructor teaching an asynchronous online course.

I'm experiencing the glitch in Chrome (and other browsers) where, if you attempt to edit a quiz answer in HTML - the 'Toggle Editing answer text in HTML' button - (necessary for superscript and subscript options, which I do need since I teach chemistry) the browser simply jumps up to the top of the page. This suddenly started happening while I was working on a quiz. Logging out, closing the browser and reopening it doesn't seem to help. 

I've seen others report this issue but there have been no solutions or responses from Canvas support. I am currently writing my final exam and this is a major issue; I'm not 100% I can complete it in a satisfactory fashion at this point. Please advise.
