Apologies for the somewhat bloated reproduction (Rollup is not a direct dependency) but I stripped away as much as I felt was reasonable from a project that have this error.
There is a PR in the cssstyle repository with a workaround that pinpoints the error but it will not be merged (jsdom/cssstyle#268).
