Re: [csswg-drafts] [css-variables] When does substitution occur, before or after animation interopolation?

@tabatkins @shans 

I've looked at the Houdini minutes and there was a breakout session 
regarding this but I can't seem to find minutes. At any rate, 
basically I'm trying to understand what the preferred expectation is 
regarding the following code:

```
div {
  --foo: green;
  background: var(--foo);
  animation: test infinite 1s;
  width: 100px;
  height: 100px;
}

@keyframes test {
  from {
    --foo: blue;
  }
  to {
    --foo: yellow;
  }
}
```
Should the div be: 
* green (what FF/Chrome currently does)
* blue
