Often (as here) the libraries just aren't available on older versions of
Windows, so it broadly makes sense.

Right, so it needs child window rendering, aka bug 45277. I guess we end up
going through GDI if that's not available, but that would be rather slow. There
are some patches linked to that bug that might help, although that area is
being thrashed a lot lately so I'm not sure if there's anything that currently
applies...
