display:contents is neither an inline, nor block type display, so this looks
wrong even if it works. How did this work for other replaced content like input
elements in your other CL? (or was the csswg imported replaced content test
skipped?)

Replaced content was ignored in that CL, but actually I've been going through
the spec and I need to make it compute to inline for those (this was recently
changed[1], in Gecko's implementation display: contents is just ignored).

Would you be fine landing this as-is a temporary measure and I'll make that
change either with all the other style adjustment changes in that CL, or in a
followup CL?
