🐞 Bug report

Description

I have a theme color for prefers dark and prefers light color schemes. Webhint flags this as invalid.

    <meta name="theme-color" media="(prefers-color-scheme: dark)"
      content="#13171a" />
    <meta name="theme-color" media="(prefers-color-scheme: light)"
      content="#f8f4f0" />

A 'theme-color' meta element is not needed as one was already specified.
