Bug Report: `JSONSchema.make` Fails with `S.filter` and `S.extend` Combination

const SchemaA = S.Struct({
  foo: S.Number,
})

const SchemaB = SchemaA.pipe(S.filter(
  ({ foo }) => foo > 0, 
  { jsonSchema: <snip> }
))

const SchemaC = SchemaB.pipe(S.extend(S.Struct({
  bar: S.Boolean,
}))

console.log(JSONSchema.make(SchemaB)) // works fine
console.log(JSONSchema.make(SchemaC)) // throws Error: Missing annotation
