Currently grid computes the alignment context for first/last baseline aligned items as follows: auto spanForBaselineAlignment = align == ItemPosition::Baseline ? span.startLine() : span.endLine() This is not correct because items that are in the same track with different baseline alignments are technically in the same alignment context. As a result, items in the same alignment context can be in the same baseline sharing group is their baseline alignment preferences are compatible https://drafts.csswg.org/css-align-3/#baseline-terms
