Description

Prerequisites

What theme are you using?

core

Version

5.x

Current Behavior

We can define an enum with oneOf:

{
      "oneOf": [
        {
          "const": "empty",
          "title": ""
        },
        {
          "const": "active"
        }
      ]
}

But if the title is an empty string, the const value is used.

Expected Behavior

The empty string option is used instead of falling back to the const value.
