So items 2 and 3 need to be 40 px as that is the height of the grid row 1. Item 5 is a simple 30px too as that is just the height of the second row. Now the subgrid requires special attention. We first need to calculate the height of the subgrid, which is the row 2 + gap + row 3 heights. Row 2 is a height of 30px, so 4a and 4b I would expect to add up to that. Row 3 is similar a height of 20px, so we need to set 4c. Now, we are losing a single pixel as these seem to be resolving to 29px for row 2 and 19px for row 3 heights. 2175897 1 webkit-bug-importer 2026-01-28 11:43:39 -0800 <rdar://problem/169113705> 2175898 2 brandonstewart 2026-01-28 11:45:06 -0800 Pull request: https://github.com/WebKit/WebKit/pull/57428 2176163 3 ews-feeder 2026-01-29 05:12:22 -0800 Committed 306411@main (7e6b3bf3ceff): <https://commits.webkit.org/306411@main> Reviewed commits have been landed.
