Thanks for the analysis here -- it indeed seems like a much more complex
problem than I'd assumed.

I guess we should just document that face remapping doesn't work
reliably when remapping parent faces to the basic faces?

And for this bug report, the answer is "you have to use mode-line-active
instead of mode-line".
