Roll back r9115, which breaks things, until we have time to not make it break

things. This whis was committed with the intention of supporting things like 
#1285, which also didn't get into 2.8, I don't think this will be a problem.
All tests still pass, and now the gutter example works. (Closes #2052) 
(See #1496)
