Expected Results: I'm not 100% certain, but probably 1. At any rate, if one comparison yields 4 (or 5) then the other should yield 2 (or 3) for symmetry. 834720 1 richard.gibson 2013-02-16 08:12:48 -0800 jQuery ticket: http://bugs.jquery.com/ticket/13331 Workaround: https://github.com/jquery/sizzle/commit/1c8aec91284af8d8c14447976235d5dd72b0d75e 835456 2 mkwst 2013-02-18 07:05:36 -0800 http://dom.spec.whatwg.org/#dom-node-comparedocumentposition says that nodes that aren't in the same tree ought to return "the result of adding DOCUMENT_POSITION_DISCONNECTED, DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC, and either DOCUMENT_POSITION_PRECEDING or DOCUMENT_POSITION_FOLLOWING, with the constraint that this is to be consistent, together". 835459 3 188880 mkwst 2013-02-18 07:14:41 -0800 Created attachment 188880 Patch 835461 4 mkwst 2013-02-18 07:16:16 -0800 Let's see what the bots say. 835484 5 mkwst 2013-02-18 07:52:10 -0800 Hey Dimitri! After https://bugs.webkit.org/show_bug.cgi?id=103502 it seems like you might be in a good position to review this change, which seems to be addressing a similar problem.

No need to calculate common ancestors :) Maybe that's better and clearer? Those are compared, like two if-blocks up (line 1179). It didn't seem to have the semantics I needed since it didn't trigger in this case, but its quite possible I misunderstood the code. Since the ancestor chain is generated regardless, this seemed like a fairly low impact mechanism. 835562 8 188880 dglazkov 2013-02-18 09:31:58 -0800 Comment on attachment 188880 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=188880&action=review >>> Source/WebCore/dom/Node.cpp:1792 >>> + // If the two elements don't have a common root, they're not in the same tree. >> >> You can do this much earlier by simply comparing treeScope() values.

You're right. A Document vs. DocumentFragment case will pass treescope check. 835583 9 188880 mkwst 2013-02-18 09:55:24 -0800 Comment on attachment 188880 Patch Thanks Dimitri!
