This would somewhat be in line with the hash tables built by the
"colors" function ... which is both a plus and a minus, because I'm
already tired of explaining that prompts et al. do not use $color
internally.

If you choose to disable bleed-over, please have a look at the way
Functions/Misc/sticky-note applies its background coloring and adjust
if necessary?  I've never really spent any time understanding
zle_highlight, and although "vared" has options to set the prompts any
highlighting would (I think?) have to be done in the line-init and
line-finish widgets if the prompts can't bleed?
