You can control this via glyphless-char-display.  The thin 1-pixel
space is just the current default, and we could change that default if
we think it's better not to display the variation selectors at all.
It's just that the "Emacsy" way is not to conceal any characters from
the user, so the current default was chosen to follow that.
