@TalbotG noticed that Blink paints the area below a baseline-aligned highlighted image, but Firefox does not. Currently the spec only allows painting highlights within the border box of an image; should we adjust it to allow painting within the full height of the line box for inline replaced elements or somesuch?

This is intentional, Blink wants to paint the whole line box, and also gaps between lines when lines wrap.

I believe WebKit has the same behavior too, no? @litherum

Epiphany Technological Preview 3.34.0-32-g514d1bfb6 (WebKitGTK 2.26.1) has the same behavior as Blink (Chromium 78 and 81); it paints the whole line box.
