Ohh no! But thank you for clarifying Jen. I’ll go ahead and file an issue for my site.

That said, dropping support for `theme-color` feels like a step back. Am I mistaken or does this go against the backwards compatibility design principle?

More than *anything* the people who actually know how technology works, who actually build things, wish that people would treat LLMs like every other technology, and be normal about them. Don't build a religion about them, don't force them on people, don't ignore the problems. Just be normal.

Thanks for pointing that out!

I just tested it Safari and Firefox. In Safari, `-webkit-fill-available` behaves just like the value `100%`. In Firefox, `-moz-available` seems to be ignored entirely.

Don’t forget the Firefox fallback!

```css
.element {
height: -moz-available;
height: -webkit-fill-available;
height: stretch;
}
```

I just tested in Safari Technology Preview 224 and it looks like the issue is finally resolved. Thank you to everyone involved!
