If the CSS "display" property is set to "none" for a particular element,
then perhaps the characters in adjacent displayable elements should not
be joined to the characters in the "display: none" element.

Perhaps the spec could say that an implementation MAY honor such things
as a color change (which may not be possible in current font
technologies such as OpenType?) or MAY instead use the isolated forms of
the individual characters. I don't know whether the obligatory ligature
rules should trump the style rules.

Here again, shouldn't the style rules trump the Unicode rules?
Otherwise, why should we even allow tags to be inserted between such
