css - textarea::selection and ::-moz-selection

Question

Is there a way to apply the ::selection and ::-moz-selection CSS pseudo-elements to the text inside a textarea?

textarea::selection {
    color: #ff0000;
}

Isn't working

Answer 1

According to this, it should work.

Can you try giving it an !important?

Can you try applying it to a different element than a textarea, e.g. a div? If it works there, it works differently for input elements - but I can't find any resources mentioning that.
