By stenington:

Actually `> div:nth-of-type(1)` is not always the same as `div:nth-of-type(1)` which was the source of the bug. The latter seems to find the first div *anywhere* in the DOM tree whereas the former finds the first top-level div. I'm not sure it's possible to differentiate in the code when it's ok not to include the leading > though, and in this context it doesn't seem to hurt.
