I don't see how it would be less confusing: the invisible characters
are invisible, so figuring out why some ellipses are in black, others
in blue, still others have some non-default background colors, and
some use a different font, sounds like mission impossible to me: you
don't see the text that gives the ellipsis its looks.

I'm not sure I understand what exactly are you proposing to do.  We
cannot treat invisible text like we treat character compositions, each
one invokes a very different machinery with distinct and very
different features.
