Created attachment 271751 [details] Reduction In the attached HTML file, inspect the first cell of the first table and change the line-height from 3 to 1.17 (or any other value less than 3) Expected: The two tables would have the same heights (if 1.17 was used). Actual: The old baseline offset calculation is retained. The first table remains taller.
Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
