autoprefixer: `background-clip: text` doesn't get expected vendor prefix

Hello 👋 I was trying to get the necessary vendor prefix for the background-clip property using https://autoprefixer.github.io/.

Input:

p {
  background: coral;
  background-clip: text;
  color: transparent;
}

Expected Output:

p {
  background: coral;
  background-clip: text;
  -webkit-background-clip: text;
  color: transparent;
}

Current Output:

p {
  background: coral;
  background-clip: text;
  color: transparent;
}

According to caniuse, support for Firefox, Chrome and Safari can be achieved by using the unoficial: -webkit-background-clip: text
