WebKit stops prefixing

WebKit ends its use of prefixes following Microsoft’s decision to make Edge support WebKit prefixes


WebKit’s new feature policy is to implement experimental features unprefixed, behind a runtime flag.

We’ll be evaluating existing features on a case-by-case basis. We expect to significantly reduce the number of prefixed properties supported over time but Web compatibility will require us to keep around prefixed versions of some features.
