1350857 - stylo: Stylo supports calc() in a bunch more places than Gecko.

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement, P5)

Description

[Emilio Cobos Álvarez (:emilio)]

As noted by Cameron in https://github.com/servo/servo/pull/16144, stylo supports calc() everywhere the spec says so, including all <angle> units, <integer>, <number>, ...

There are a bunch of them that aren't supported in Gecko right now. We should evaluate this, and decide whether we want to ship it or disable parsing calc() in a bunch of those.

I don't think this really matter as far as there is no evidence that this breaks anything.

Moving this to blocking bug 1365771 instead.

There are a bunch of DevAdvocacy issues around calc() compat in bug 1376206, would be fantastic if they're fixed in 57 via Stylo!

Firefox has used stylo for some time now.
