Description
https://copierdoctor.com.au/ had UCSS disabled, so I enabled it, purged the cache and looked at it again. Styles were different.

I then compared the page with CCSS and without, and CCSS gets lower scores from Lighthouse.
Without CCSS:

With CCSS:

Research direction
Reproduce the reported page at https://copierdoctor.com.au/ with UCSS disabled and enabled, then compare the styling of #primary-nav-select and .flex-control-nav. Compare Lighthouse results with CCSS enabled and disabled; done means UCSS preserves the expected styling and CCSS no longer lowers the reported scores.
