Describe the bug you're encountering

in the preview for the users GET request, not all fields are displayed.

To reproduce...

paste the above swagger file into the editor and see the rendered result.

Expected behavior

all fields should be displayed which are defined in the swagger file.

Screenshots

this is the output with missing fields:

also the schema is not displaying those fields:

interestingly enough, in the Schemas section of the editor, everything gets resolved properly:

Additional context or thoughts

I searched if some similar bug is/was happening already, the closest i found were https://github.com/swagger-api/swagger-editor/issues/1892 and https://github.com/swagger-api/swagger-js/issues/1394 but for the first one, i'm not sure if its the same issue. and changing the order also does not help here in this case.

the problem arises, when a list/array has items of objects, which are composed by other objects (referenced with allOf), which in turn also already were built out of other objects.

why do i need this? the shown swagger file is actually the condensed version of our system, which contains a user permission model. we need those different levels of inheritance to properly document also POST and PATCH requests.

Reproduce the issue by pasting the provided OpenAPI definition into Swagger Editor and compare the rendered users GET preview and schema with the resolved Schemas section. Trace how nested array items and chained allOf references are rendered; done means all inherited fields appear in both the preview and schema displays.
