I think our implementation is fine here; this is just a bug in the test, which needs a rule:

 html, body { height: 100% }

Hi,

I was able to confirm the issue, and I think you are right here about the fact the body element does not need to fill the viewport in this case (though I am not sure whether a spec requires it or not).

I'm happy to report I fixed that in the test, because this issue is not relevant to the test anyway.

Microsoft Edge is now tracking the issue as #104867: <body> element sized to viewport, rather than zero height. I am not sure when we will be able to provide a fix for the issue, though. Since we match Chrome, it is likely this issue will never get fixed, so I would encourage you to log the issue on your end, too.

If you could possibly look for a specification invalidating Edge and Chrome behavior, that could help fixing this issue. Otherwise, maybe you might want to match. I'll leave that up to you.
It doesn't seem to me you match Chrome. I just tested Chrome, and it seems to me it shows a whole page of red for the original test as well.
Interesting. The bug did include a test case where we matched Chrome on this.
I should try to dig this deeper, thanks for mentioning it.
Ok, final comments here is that we match Chrome in Quirks mode, and Firefox matches Chrome in standards mode.

- Edge: Body always fills up the viewport
- Firefox: Body never fills up the viewport
- Chrome: Body fills up the viewport only in quirks mode
