Apologies, I have reverted the merge that I think is related https://github.com/styled-components/styled-components/releases/tag/v6.1.10

[eMerzh]

correct, it fixes the issue, thanks for the response :)
and thanks @uhyo for the attempt, even though we have to revert it.
you only break stuff if you do stuff :)
