There's a shortcut in place that uses the root selector as the context for the rest of the selector if the root selector uses an id. Later there was logic that used the context's parentNode instead if the first part of the selector was hierarchical; it was designed to handle selectors like Sizzle("> div", context) (e95367f).
The parentNode logic was only being used when the parts length equaled 1. That didn't account for selectors like $("#dialog ~ div button:contains('next')"). Changing the parentNode logic to apply when the parts length >= 1 fixes the issue.
I added a test for this new selector and checked that all the other tests pass.
