(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

This looks very similar to the problem in bug#44784, and the issue there
was that Emacs was choosing a font for ̷ that's not the same as the font
used for 0 -- in that case Emacs doesn't combine chars.  So it's a
matter of choosing a font that has wider coverage, I think.
