HTML: make sure the default opacity of ::placeholder is 1

This test relates to the opacity difference in between Gecko, Blink and WebKit as mentioned by @fvsch

/* Gecko style */
::placeholder {
  color: inherit;
  opacity: 0.54;
}

/* WebKit style */
::placeholder {
  color: #9a9a9a;
  opacity: 1;
}

/* Blink style */
::placeholder {
  color: #757575;
  opacity: 1;
}
