Issue #1671 - Unprefix ::-moz-selection
This actually keeps both pseudo-elements for now, since the prefixed version is still used internally, but we need the unprefixed version for web compat. Note: while unprefixing a non-spec-compliant pseudo here, it's exactly in line with what other browsers do. Nobody is following the spec here and at least we'll be doing what everyone else is with our unprefixed version.
