css.at-rules.media.range_syntax - Incorrect support from Firefox

[Antonio-Laguna]

What information was incorrect, unhelpful, or incomplete?

It's said that Firefox 63 added support for this. However a media query such as

@media (480px > width > 768px) {
  body {
    background-color: pink;
  }
}

Does not get executed. Simpler media queries seem to work such as width <= 480px but these ones do not:

What did you expect to see?

I'd have expected to see a note on partial support on that table

Did you test this? If so, how?

I tested with a simple Codepen https://codepen.io/antonio_laguna/pen/NWaVpeG on Browserstack on 63 and current version both on Windows and Mac.

Full support seems to have shipped in Firefox 102.

Tested with window.matchMedia('(1px < width < 99999px)')
