Expanding a selector list leaves two rules on one selector that neither endpoint can host: folding the earlier one forward passes a write that observes it, folding the later one back passes a different one. A position between the two is legal for both, since each then crosses a shorter interval, so a factored sheet reaches the shape an unfactored one starts from instead of canonicalising to a different one.

expand_listssplits a selector-list rule into one rule per selector, which can leave two rules on a single selector that neither end of the pair can host: folding the earlier one forward passes a write that observes it, and folding the later one back passes a different one.coalescetested only those two endpoints, so it gave up while a position between them was legal for both, and a factored sheet canonicalised to a different shape from an unfactored one.--diff=canonicalthen reported the second rule's declarations as missing.On the tailwindcss.com comparison this closes eight phantom entries, the four
