The issue seems to be that CSSGlobalVariables use native dom and therefore require a browser context, but Jest seems to execute it before the browser context is loaded. If that hypothesis is true, then to solve this issue, this library would need to expose an optional flag that await that e.g the root dom node has loaded before executing, or at least that do nothing if the DOM is not loaded.
