9px is the default minimum logical font size. So are you implying that the change you are planning for bug 174406 will affect the line height in all apps that don’t set a non-default minimum logical font size?

Isn't that the whole point of the patch? To make minimumFontSize and minimumLogicalFontSize affect line-height?

I guess the bug is about the accessibility font sizes, which set minimumFontSize but not minimumLogicalFontSize. This means I have to rethink my approach in https://bugs.webkit.org/show_bug.cgi?id=174406.

(My current approach was to treat the calculation of the computed font size as a black box, and simply query it's value and the value of the specified font-size, and then make line-height scale up accordingly. However, if I'm going to treat certain parts of the computation of the computed value of font-size differently from other parts of the computation, this approach isn't going to work.)
