Describe the bug you're encountering

https://editor-next.swagger.io/ outputs the warning:

maxLength has no effect on non strings

and thus it is not shown. I don't mind if a warning is emitted but the maxLength should not just be stripped from password

To reproduce...

Steps to reproduce the behavior:

1. Go to maxLength has no effect on non strings
2. Paste the example above
3. See warning at the bottom left

Expected behavior

swagger-ui should not try to outsmart the creator of the spec. The above example is valid so swagger-ui should show all properties

Screenshots

Additional context or thoughts

Reproduce the issue in editor-next.swagger.io using the provided OpenAPI schema, then trace the warning and schema rendering path for maxLength on the password object. Done means the example's maxLength remains visible for the non-string property while the existing behavior for the string property is preserved.
