2017 Code Coloring - code within code problem

Old versions of color coding worked in such that comments within comments color coded based on the matching end.  Now it looks like it only matches until any matching end no matter if it is not really the paired end. So the resulting action is the comments coloring would be applied to the 1st set but it should look like the 2nd below.  Seriously 2017 is a major pain in the ass so far.
