For those who are following this issue about /deep/ and '>>>' combinator,
here are the status as of now:
- /deep/ is for Shadow DOM v0 and still available in Chrome, but deprecated.
- '>>>' is implemented for querySelector (not for CSS) behind the flag
(chrome://flags/#enable-experimental-web-platform-features) on M56+.
Only works for V1 open shadows.
- https://github.com/w3c/webcomponents/issues/78 is the active thread to
discuss this in the spec.
Apple recently proposed an idea of new API
(collectMatchingElementsInFlatTree).
