> The overlay property has not been implemented outside of chromium yet, and it can be removed from chromium without breaking existing top layer exit animations to display:none which already specify the overlay property.
Wouldn’t this break existing demos that use snippets such as this one here (swiped from [this article](https://developer.chrome.com/blog/entry-exit-animations))?
```css
.card {
transition: opacity 0.5s, display 0.5s, overlay 0.5s;
transition-behavior: allow-discrete; /* Note: be sure to write this after the shorthand */
}
```
Perhaps a tweak could be that the property is allowed in such declarations, but no longer mandatory for the effect to work?
