Description
Work on #10868 revealed this error in oldSizzle: http://jsfiddle.net/JBBM8/
Because Sizzle.selectors.relative functions "return" only a single match, Sizzle can be trapped into a false negative with respect to preceding parts of the full selector when the relative selector tests against multiple elements (e.g., "~" and "").
I'm pretty sure that fixing this will require changing the Sizzle.selectors.relative Extension API to allow "returning" arrays, so I will hold off working on this until the core team weighs in with their comments/approval.

Can you coordinate with timmywil on this? He's got #10697. I'll mark this one as a dup but really it seems like this should be filed as a Sizzle bug.

Reopening as this was not addressed in the rewrite. Here is another test case that i think is related:

OK, it seems the sibling issues from nwbox are already fixed, so those aren't related. However, there is still an issue with deeper levels. The fiddles are still valid.

A combination combinator fiddle for the masses: http://jsfiddle.net/timmywil/WSrGh/. Working on it.

Update Sizzle. Fixes #11109.
Changeset: 8763bec032bc2dc10bf0d6686b820b731b525091
Technical explanation: Given a query like
"A + B ~ C", Sizzle:C, thenSizzle.selectors.relative["~"]to replace each element with the first preceding sibling element matchingB(orfalseif nonexistent), thenSizzle.selectors.relative["+"]to replace each element with the preceding sibling element if it matchesA(orfalseif it doesn't), thenfalsethrough all subsequent stepsThe problem here is that step 2 fails to report back all preceding siblings matching
B, erroneously restricting the input set for subsequent step 3.
