inconsistent redoc html with request sample type being multipart/form-data

Describe the bug
When the request sample is of type multipart/form-data the redoc html rendered for the spec is not consistent with what gets rendered for application/json

Expected behavior
Rendered html should be consistent or similar

Minimal reproducible OpenAPI snippet(if possible)
sample.txt

Screenshots

Additional context
If you check the screen shot, on the left the rendered html for request type application/json has a div with class redoc-json
on the similar lines if you check the right side on the screen shot for multipart/form-data request type redoc does not generate the div with class redoc-json like it did for request of type application-json but when request type is changed from multipart/form-data to application-json it works as expected, the html gets rendered as expected that they are similar, not in consistent

is this a bug or how can it be addressed?

Please let me know, thanks

Start by opening the attached sample.txt and comparing the generated HTML for application/json and multipart/form-data, focusing on the redoc-json element described in the report. Reproduce the rendering difference, then verify that both request samples produce consistent HTML behavior.
