Description Antoine Quint 2020-01-13 06:08:52 PST 
There are still some issues to iron out with Animation.timeline being a read-write property, so we should follow what Firefox and Chrome do and make it read-only alone for now.

Cc'ing Chris Dumez and Sam Weinig for guidance about how to make a property read-only by default and read-write only if a given runtime flag is enabled. I don't think our code generator supports this at the moment.
