(See e.g. https://github.com/web-platform-tests/wpt/commits/master/css/css-text/parsing/letter-spacing-invalid.html which hasn't had any commits in the past six years.) 2017998 1 gsnedders 2024-03-01 06:47:16 -0800 I don't know if https://github.com/web-platform-tests/wpt/pull/44882 resolves all of this? It probably doesn't cover the CSS1 test change? 2017999 2 webkit-bug-importer 2024-03-01 06:47:42 -0800 <rdar://problem/123898511>
