angular 5，reactive form-重置所需的表单控件不会重置输入下的所需错误

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormControl, Validators } from '@angular/forms';

@Component({
  selector: 'app-my-form',
  template: `
    <form [formGroup]="myForm" (ngSubmit)="onSubmit()">
      <input type="text" formControlName="name" placeholder="Name">
      <div *ngIf="name.invalid && (name.dirty || name.touched)">
        <div *ngIf="name.errors.required">Name is required.</div>
      </div>
      <button type="submit">Submit</button>
      <button type="button" (click)="resetForm()">Reset</button>
    </form>
  `,
})
export class MyFormComponent implements OnInit {
  myForm: FormGroup;

  constructor() { }

  ngOnInit() {
    this.myForm = new FormGroup({
      name: new FormControl('', Validators.required),
    });
  }

  onSubmit() {
    // 处理表单提交逻辑
  }

  resetForm() {
    this.myForm.reset();
  }

  get name() {
    return this.myForm.get('name');
  }
}
