Describe the bug you're encountering

Tried to use 'content' to describe a query parameter with type array of objects but its not working.

Example use case: ?sort=[{"property":"date", "direction":"ASC"}]

Expected behavior

Or like this (when clicking add item, it should add the single object schema):

Screenshots of what I got

Its all blank:

Related issue: https://github.com/swagger-api/swagger-ui/issues/4442
That issue solved the content rendering but only for simple json objects.

Start by reproducing the supplied OpenAPI 3.0 query-parameter example in Swagger UI 3.25.0 and compare it with the behavior described in related issue #4442. Trace the existing content rendering entry point and its tests, if present; done means an array of objects renders and can be added as the expected schema shows.
