This change is from w3c/css-houdini-drafts@5261c1a. @tabatkins, is it still on some other level? It's still in https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/css/cssom/css_position_value.idl, FWIW.

Ping @tabatkins on the fate of CSSPositionValue. Note that it's still in https://github.com/w3c/css-houdini-drafts/blob/03743d14fcecb2c3700e7002a92d9283f5bb8a17/css-typed-om/README.md.

No, it's been removed from this level due to it being known to be inconsistent with already-specced upgrades to <position> values (to accommodate logical directions). The design assumed that the position could always be expressed in physical coordinates, which absolutely isn't true for specified values, and isn't necessarily true even for computed values.

I need to remove it from some other places that still reference it, but it won't return until we fix the object's shape.

@tabatkins, can you file bugs for unshipping the interface in Chrome and removing tests for it here in WPT?

[tabatkins]

yeah
