説明

I have searched the existing issues
I understand that providing a SSCCE example is tremendously useful to the maintainers.
I have read the documentation
Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

core

5.x

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.

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

調査方針: Start by examining the provided playground link to understand the schema and expected behavior. Locate the code that renders enum options with titles, likely in `EnumWidget` or `SchemaField`. Look for a condition like `title || const` that incorrectly replaces an empty string title with the const value. Adjust the logic to preserve the empty string title when explicitly set.
