[fxtf-drafts] Clarify `offset-position` creates stacking context or not? (#609)

== Clarify `offset-position` creates stacking context or not? ==
Hi Team,

Just raising to clarify about behavior around `offset-position` because currently it creates stacking context (will-change: offset-position) in Chromium but not in Safari and Firefox.

Test Case: https://jsfiddle.net/6xkwroL0/

WebKit Bug: https://bugs.webkit.org/show_bug.cgi?id=293845

Web Specification: https://drafts.fxtf.org/motion-1/#offset-position-property

It is not clear in specification, if it shouldn't, I can raise bug on Chromium tracker while if it should, I will raise it for Firefox / Gecko and will try to fix in WebKit.

Thanks!
