The spec issue, https://github.com/w3c/csswg-drafts/issues/3503, is resolved by a more restrictive rule for now:

> Define repeat interpolation using the more restrictive rule in https://github.com//issues/3503#issuecomment-453674839


It could be loosen, but for now we should follow the restrictive rule:
 * require that the first arg is a number, and identical between start/end; different values, or keyword values, both go discrete

That means we have to fix this bug to match the updated spec and fix the wpts [1]/[2], which uses a loosen way if the first arg is a number (because Gecko uses an incorrect computed value of repeat()).
