Annotation Issues with Transformation and JSON Schema Generation

Schema.Struct({
  email: Schema.optional(EmailForm, { as: "Option", exact: true }) // without Schema.optional it works as expected
})
.annotations({
  title: "👤 Visitor",
  description: "description",
})
// produced json-schema
{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {...},
  "additionalProperties": false,
  "title": "Struct (Encoded side)" // expected "👤 Visitor" + description
}
