Research direction

Start by reproducing the failure in the linked CodeSandbox, focusing on the demo.tsx example and the interaction between experimental_sx and pseudo-classes. Trace the relevant styling entry point from there and verify that the pseudo-class style works when experimental_sx is used, matching the behavior when sx is removed.
