Describe the bug

ConfirmEmail.cshtm does not use the returnUrl paramter in the confirmation URL.

Register.cshtml.cs sends an email to confirm the user. The email contains a confirmation link to ConfirmEmail.cshtml. The confirmation link includes three parameters: userId, code, returnUrl

https://FQDN/Identity/Account/ConfirmEmail?userId=12345678-f866-43dd-bbb8-710616122ce2&code=12345678ZFhkV3hmUTVoS3ZqbUhRYXhkQ0lXM0ZYd3BoVWhvKzJYNFZwck5CUUdzVXFWMFlOY2RpTE8vK1pnd25mNkVsQXlobnVteW95UlovMWtSdjBHQzFoTWFpSkdoSFg0OHlTVGhLVXVjMlVib0ZOMXg1bVdzeEZaOFpyWSs1TW5veWw3S21maGNLU1ZrSDRCeEFBaUpWYTdrNWNrcm5VWkRGOGtTQzJMWlJUK1VablhDdDVheGdmMjNtMzJZeVVaTjV0VEZmVCtENWQwdzhia0taNTd2MHRvWTZZMEYwak5wcGZveVZGdFRwSy9ReHJBSTR2YTVLVmVnZmFaMVZ3bi93dz09&returnUrl=%2FProfile

var callbackUrl = Url.Page(
 "/Account/ConfirmEmail", pageHandler: null,
 values: new { area = "Identity", userId = user.Id, code = code, returnUrl = returnUrl },
  protocol: Request.Scheme);

 await _emailSender.SendEmailAsync(Input.Email,  "Confirm your email",
  $"Please confirm your account by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");

ConfirmEmail.cshtm.cs OnGetAsync signature only is using two parameters:

public async Task<IActionResult> OnGetAsync(string userId, string code)

So the returnUrl is never processed.

Expected Behavior

After users email ti confirmed should be redirected to the return URL.
