Description
As a user, I want to get notified if my browser is incompatible with CodeOcean. In that case, I expect a clear warning message providing me some hints on what to change.
This feature has already been prepared and was active some time ago, but is no longer working as intended (or the browser list is outdated). That should be checked and fixed.
We could always check with IE 11, which is unable to render the ACE editor when implementing an exercise.
