Bug 258868 changed the baseline computation to just using `height`s, which may be slightly incorrect. sgill26 said in https://github.com/WebKit/WebKit/pull/15558#discussion_r1254875925 : One thing I'm wondering is if we should be using the margin box for the renderer here? I was looking at the other implementations of baselinePosition and they all see to return a value in terms of the margin box, but here we are using the border box.
