Mark a reference combinator spec as ending at 3.4.

Skip ruby-sass

It's worth noting that removing support for reference combinators without adding support for the >>> combinator will prevent Sass working with Angular. More details in

sass/libsass#2378 and sass/sass#2266

According to this Chrome platform status page:

Shadow-Piercing descendant combinator, '/deep/' (aka '>>>'), including '::shadow' pseudo elements, are being deprecated.

However, the CSS Scoping 1 spec, which was updated today, still includes >>>. @tabatkins, can you provide some more context here? Is >>> deprecated or not? Is it supported in Chrome? Will it continue to be?

[tabatkins]

Deprecated in style sheets; it's no longer allowed there per spec. Still allowed in querySelector()/etc.

[nex3]

In that case, it sounds like Angular should no longer be using either /deep/ or >>> in their style sheets, so we shouldn't feel obligated to support them.

[tabatkins]

Yup, exactly.

@nex3 Mind if i ask, if they remove such selectors for nested items, with what should they replace it?

[tabatkins]

Whatever they're already using to make it work in browsers other than Chrome, presumably.
