And I don't understand what problems you see.  I don't think you
described them in enough detail.

What do you mean by "compose linearly"?

Emacs can only compose characters if all of the characters of a
composable sequence are supported by the same font.  It is
practically impossible to compose character glyphs from different
fonts, so Emacs doesn't.  If that's what you see, then it's the
intended behavior.

If those "other fonts" cause the characters in a sequence not to be
supported by a single font, then again, this is the intended behavior.
