[Bug]: No maxLength label is displayed for arrays of items

[kosanna]

Hey there, it seems there's some bug with rendering maxLength badges on array of items described by a schema.

Sample json property

        "bullets": {
          "type": "array",
          "items": {
            "type": "string",
            "maxLength": 80,
          }
        },

Expected behaviour: <=80 characters badge is displayed
Actual:

redoc-cli v0.10.4

Note:

• Could not find anything that says it's been fixed in subsequent version.
• Also could not find any migration guide from 10 to 11, seems to be breaking.

Any advice or help is greatly appreciated. Thank you!

Instead of creating new issue just making confirmation on array items string type rules.
Confirming redoc-cli v0.12.2 has same behavior, pattern, description, minLength, maxLength rule badges are not rendered.
Enum rendered.

starts:
    type: array
    items:
      type: string
      description: "My start list"
      minLength: 3
      maxLength: 100
    maxItems: 12

starts:
    type: array
    items:
      type: string
      description: "My start list"
      pattern: /([A-Z])/
    maxItems: 12

It seems enum rule works:

starts:
    type: array
    items:
      type: string
      enum: [Jr. Test, Dr. Tester]
    maxItems: 12

Maybe pattern, description, minLength, maxLength string rules should be rendered same as enum rule.

With pattern, minLength, maxLength string rules
Items pattern: A-Z
Items length: [ 3 .. 100 ] characters

With maxLength string rule
Items length: <= 100 characters

With minLength string rule
Items length: >= 10 characters

I don't believe the current implementation will show constraint badges for array item types.

In situations where constraint badges appear next to array-based fields, they refer to the constraint applying to the array itself. An example is maxItems, as pointed out in a previous comment.

The additional problem here is how best to present the array item type constraints.

A naive (and I think quick) solution would be to collect and stack all array item type constraints adjacent to array constraints. However, this mightn't read intuitively.

Example:

Array of strings [<= 3 items] [<= 80 characters]
...

@RomanHotsiy, if you've got any opinions on how best to present the array item type constraints, I can have a shot at making changes to support them.

I believe there is a PR already in progress related to this but I have to check if this is considered. See the mentioned PR above.
