1737211 - WPT test translate-interpolation.html fails in Firefox

Status: RESOLVED FIXED

(Core :: CSS Transitions and Animations, defect, P3)

Description

[Daniel Holbert [:dholbert]]

Filing this bug for this WPT test-failure:

https://wpt.fyi/results/css/css-transforms/animation/translate-interpolation.html?label=master&label=experimental&aligned&q=firefox%3Afail

There are 3 failures, which are really all the same failure:

!EQ("480px 400px 320px ",
    "calc ( 0 % + 480px ) calc ( 0 % + 400px ) 320px ")

We're apparently serializing this intermediate value using calc(0% + ...) syntax, when the test is just expecting the pixel part of that value, without the unnecessary calc(0% + part.

This test happens to be part of the compat2021 testsuite; marking as blocking that metabug.

This is a bug in the test. 0% should never be stripped from calc().

Stripping the percentageness from calc() interpolation is not correct,
