Bug 238746 – Update 'features.json' for current state of WebKit

• Component: WebKit Website
• Status: RESOLVED FIXED

[Brent Fulgham]

I noticed that the current 'features.json' file is out of date. I think the attached changes more accurately reflect the state of the engine.

I would just remove this `"enabled-by-default"` line.

Not sure why ::grammar-error has single quotes.

specify a path -> specify position along a path. Remove "The time may be static if no animation was specified."

Supported

Some scroll containers may be part of a containing block chain but may serve a different logical purpose in the document and may want to prevent scrolling from continuing up the scroll chain.

I would just say:
"Allow authors to control whether scrolling results in overscroll ("rubber-banding") and propagates to enclosing scroll containers."

Do we support the SpeechRecognition part of this? I don't think so, so In Development.

We do! That was a big part of our Safari feature work for iOS 14 and Big Sur.
