1999920 - `--s: sign(100cqw - 400px)` fails without registering `--s` (works in Chrome and Safari)

Status: NEW

(Core :: CSS Parsing and Computation, defect)

Description

[Nicolas Chevobbe [:nchevobbe]]

Attachment: sign_cqw.html

In the attached page, there are 2 <section>s setting a grid-template-columns declaration with a value computed from CSS variables whose declaration are using container query unit in a sign() function.
The first section is using a registered <integer> custom property, the second one is using a non registered custom property.
In Firefox, the grid-template-columns computed value for the second section (using the non registered custom property), is 0px, in Chrome, it's 200px 200px (that might depend on body width though)
