Hi, The spec for <position> <https://drafts.csswg.org/css-values-4/#typedef-position> only accepts 1,2, or 4-valued syntax. so I'd like to retire the 3-valued positions from these CSS properties (i.e. <object-position>, <perspective-origin>, and <mask-position>). Blink retired this support in Chrome 68, and we are planning to retire them to match the spec, too.
(Note: <background-position> still accepts 3-valued syntax, per the definition of <bg-position> <https://drafts.csswg.org/css-backgrounds-3/#typedef-bg-position>.)
