[csswg-drafts] [css-viewport] [cssom] [css-typed-om] Consider adding a way of exposing the effective zoom. (#9809)

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

== [css-viewport] [cssom] [css-typed-om] Consider adding a way of exposing the effective zoom. ==
Without it, translating global to scaled coordinates is error prone (have to walk the DOM tree upwards multiplying `getComputedStyle(el).zoom`).

My preference would be a member in the computed `CSSStyleDeclaration` (might need a `CSSComputedStyleDeclaration`?) for simplicity, and / or in the `computedPropertyMap` (which IIUC would also need a new interface), but happy to hear other alternatives, maybe just `Element.prototype.effectiveZoom` or such. 

Thoughts?
