Created attachment 461482 [details] Correct behavior in Chrome It's impossible in Safari to make the following CSS work: ```css :root { --color-scheme: dark light; color-scheme: var(--color-scheme); } ``` Go to https://aboard-bustling-bit.glitch.me/ in Safari and inspect the `<input>` with the value "Just a test". Note how the computed style for the `color-scheme` is always `auto`. Run the same test in Chrome and see how it reflects what is set via `var(--color-scheme)`.

I wonder if https://github.com/WebKit/WebKit/commit/5cd7506926c2b38de056ec7dec5c62d1a049c052 fixed it by avoiding applying the property twice.
