Houdini animation api page doesn't work


Expected Behaviour

Scrolling should show animations, which are mentioned in “Try it out!” section.

Actual Behaviour
Nothing happens. Error in console: Uncaught (in promise) TypeError: Cannot read property 'addModule' of undefined

It really frustrates me! Did I miss something?

It appears CSS.animationWorklet is undefined.

But why? I am using chrome and other example websites do work.
