PostCSS Initial : unexpected behaviour for `preserve` option.

[rubycon]

Bug description

Running PostCSS initial with preserve: false on :

{
  opacity: 1;
  pointer-events: initial;
}

will result in

{
  opacity: 1;
}

The issue is that pointer-events IS NOT amongst the properties handled by the plugin and initial is a perfectly valid value. Wouldn't the expected behaviour be that the prop is preserved as a fallback if a replacement is found, as it was the case with the original plugin replace option. With the current behaviour all properties not handled by the plugin with value initial are simply stripped!

Source CSS

{
  opacity: 1;
  pointer-events: initial;
}

Expected CSS

{
  opacity: 1;
  pointer-events: initial;
}

Actual CSS

{
  opacity: 1;
}
