code-view active class being applied to PR code comment editor

What should be the styling for selected lines of code in file view (I think?) is also affecting the code editor because it ends up with the same class structure of .code-view .active

Would be nice while fixing this to also fix what ever is causing everything comment/editor related to be monospaced -- assume general issue is that the comments/editor don't actually belong in code-view class
