The rule that drops the space above it never applied to a Word document: :is(p, h1, …, .toc) takes the class specificity of .toc, so the later spacing-model rule tied at (0,4,0) and won on order — and the heading opening a two-column section sat 3.5mm below the column beside it. Zeroing the property both spacing models read settles it, and beats the block's own inline value as a margin would not. Probed: LibreOffice starts both columns level; a two-column page now matches it 45 lines deep, where it diverged at line 8.
