Entire layout shifts slightly when going between Students and Articles

Click back and forth between these, for example:

• http://dashboard.wikiedu.org/courses/Rice_University/Poverty,_Justice,_and_Capabilities_%28Fall_2015%29/students
• http://dashboard.wikiedu.org/courses/Rice_University/Poverty,_Justice,_and_Capabilities_%28Fall_2015%29/articles

@ragesoss This is because the scrollbar is appearing for the longer students page, shrinking the available screen width and shifting the content. I think that behavior is okay. The only thing we could do to prevent that is always show the scrollbar, which isn't done too often. Thoughts or concerns?

Ah, of course. Is it possible, within a single course — which acts like something very close to an SPA — to keep the scrollbar in place after the first time it appears? Just a thought.
