Trigger for redirect to url action causes email to not be sent after users register

The issue is that Action/Trigger for redirect to url action causes confirmation email to not be sent after users register. In other words after user clicks the CREATE NEW ACCOUNT button an registration email should be send to the user's email address. But the email is never send. So user can't log-in to access the Drupal site.

Steps to reproduce this issue in Drupal 7.x dev.
Go to admin/config/people/accounts Under section "Who can register accounts?" if not already done select "Visitors" option and check "Require e-mail verification when a visitor creates an account." box. Click on SAVE CONFIGURATION button.

Create a new page at node/add/page Before clicking on SAVE button. Click on "URL path settings" link. Type in a URL alias. We will need that later. In this example URL alias is confirmation.

Go to Administer » Site configuration » Actions

At the bottom of the page under "Make a new advanced action available" section. Select Redirect to URL.... Click on CREATE button.

Leave the description as is "Redirect to URL". Type in a URL. In my case I type in confirmation. Click on SAVE button.

Go to admin/structure/trigger

Click on USERS tab.

Under section "Trigger: After a user account has been created". Select Redirect to URL....

Click on ASSIGN button.

Log-out Drupal at user/logout

Go to user/register Type in a USERNAME and EMAIL. Click on CREATE NEW ACCOUNT button.

If successful you should be redirected to /confirmation page.

The issue is that Action/Trigger for redirect to url action causes email to not be sent after users register. In other words after user clicks the CREATE NEW ACCOUNT button an registration email should be send to the user's email address. But the email is never send. So user can't log-in to access the Drupal site.

Expected result is that after user clicks the CREATE NEW ACCOUNT button a registration email should be send to the email address he provided. Then user should be redirected to URL. In this example the URL is /confirmation
