I think we should unprefix -webkit-user-select.
Firefox and Chrome support this CSS property "user-select" (without prefix) since a while .
So, I think we should unprefix it and make -webkit-user-select an alias to it (which its also required by the spec: https://www.w3.org/TR/css-ui-4/#propdef-user-select )
Is there any behavior difference between what we have and the standard version?
(Also we might need to add the unprefixed but keep the prefixed for web compat).

All the bug in "See Also" are good start like copying behavior.
Given most web developers are largely blindly using -webkit-user-select alongside user-select today, do we need to block unprefixing on fixing our outstanding spec compliance issues?
