[csswg-drafts] [css-backgrounds] What is the serialization "background-position: top right 10px"? (#6586)

smfr has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-backgrounds] What is the serialization "background-position: top right 10px"? ==
https://www.w3.org/TR/css-backgrounds-3/#background-position doesn't say how the edge-relative background position values serialize (like `background-position: top right 10px`).

This is tested by css/css-backgrounds/parsing/background-position-x-computed.html and css/css-backgrounds/parsing/background-position-y-computed.html which in Gecko test that `right -10px` serializes as `calc(100% + 10px)` and `bottom -10px` serializes as `calc(100% + 10px)` but the spec does not describe this.
