Too low contrast for links when page in `color-scheme: dark`

OS Version: OS X 10.15.4
URLs (if applicable): https://color-scheme-demo.glitch.me/
Other browsers tested:
  Add OK or FAIL after other browsers where you have tested this issue:
    Chrome: Fail
    Firefox: Fail (doesn't support `color-scheme` yet)
    IE/Edge: Fail (for old IE and new Edge)

What steps will reproduce the problem?
1. Go to https://color-scheme-demo.glitch.me/
2. Note how when the page is toggled to `color-scheme: dark` all user agent stylesheet link colors (apart from :active) have too low contrast.

What is the expected result?

Link colors (except for :active) should have enough contrast.

What happens instead of that?

Link colors (except for :active) don't have enough contrast.

Since this probably requires changes to the user agent stylesheets, it would be great to agree on a cross-browser set of dark scheme default link colors.

I have opened https://github.com/whatwg/html/issues/5426 for cross-vendor awareness.
