### Additional context

_No response_

No source files, tests, or entry points are identified. Start by reproducing the problem in the new experience: open a Standard Logic App, choose Run draft with payload, and submit XML using application/xml or text/xml. Done means the draft runs with the XML payload instead of reporting that the payload must be JSON.
