Hi, I'm using a tool where the version of styled-components is locked on v5.1.1 since after that the SSR broke (#3374), but for our use-case with their tool we render components in an iframe and the issue with that only got fixed in 5.2+ (style tag renders in the parent document, not in iframe) and as far as I can tell the issue/3374 got fixed in pull/3552 (2 days ago). So a new release would be really nice.
