Styles are too easily overridden #180
Description
Not having styles applied using !important declarations makes the attribute feel less robust than I'd like.
I tried the attribute on a purely decorative map (from the popular Leaflet JS library), but in many cases pointer-events: none was overridden due to their internal use of pointer-events: auto.
In #33, some styles have !important declarations, can they all have?
Or should it be left up to the author? Similar to [hidden] { display: none !important; } (jensimmons/cssremedy#71 (comment))?
