Yes, if the background color is non-empty. Likewise, with non-default
frame color, the background color is set to white

This is not ideal (and wrong e.g. with non-white page color), but alas
\fcolorbox requires us to pass explicit colors for both frame and
background.

There are some workarounds on stackexchange for this, but all those
strike me pretty ugly.

This has been the case always, my recent work didn't change that.
