Assert css variable value?

[jkeen]

It doesn't seem like qunit-dom has the ability to check the value of a css custom property/variable, like --color-text, or whatever. Am I right about that?

I tried using hasStyle, hasAttribute, and hasProperty with no avail. In trying to make some changes for a PR, but it seems ilke the issue might be a jest / node thing?

With #1976 merged it might've been fixed, at least for the hasStyle test.

Feel free to reopen if it's not fixed.
