Struct field comments get incorrectly duplicated when using type aliases from other packages

[djui]

Describe the bug

When using a comment on a struct field with a type alias to another package which also gets replaced, this field's comment will be duplicated to other fields that should not have a comment (or their own comment).

To Reproduce
This examples will demonstrate the issue: See in the swagger.yaml the field b has a description (Comment) but shouldn't.

// main.go

package main

import (
	"database/sql"
	"net/http"
)

type Bool sql.NullBool

type Foo struct {
	A Bool // Comment
	B Bool
}

// @Success 200 {object} Foo
func handle(w http.ResponseWriter, r *http.Request) {}

# .swaggo
replace database/sql.NullBool boolean

Run:

swag init --parseDependency --overridesFile ".swaggo" --dir cmd/main --outputTypes yaml

Output:

# swagger.yaml
main.Foo:
  properties:
    a:
      description: Comment
      type: boolean
    b:
      description: Comment
      type: boolean
  type: object
