Description Chris Dumez 2022-12-22 13:05:03 PST

`transition-duration` property shouldn't allow negative values, as per:
- https://w3c.github.io/csswg-drafts/css-transitions/#transition-duration-property

This means that StylePropertyMap.set() should wrap the value in a `calc()` when negative, and that the computed value should be clamped to [0, inf].
