Investigate why the XB UI seems to not apply client-side transforms

Overview

Grab a ☕️ and go and read #3528396-20: Video prop shape: e2e test coverage for video from media library the component instance form + fix revealed bug in shape matching → .

Over there, we worked around it purely on the BE, but it's likely still a bug in the handling of client-side transforms — possibly on the BE not providing them, possibly on the FE not applying them.

We need to get to the bottom of that still, and ideally would remove the work-around that MR added.

Proposed resolution

TBD, investigate.
