A form redirecting to the post created with delay will not redirect to the created post

Symptoms

When you set a Toolset Form to redirect to the post created or edited with some delay, then the form does not redirect to that post, but keep showing the page where the form was inserted to. It also appends the `_tt`URL parameter (suggesting a success message).

Workaround

This issue is solved if you do not use a delay of redirection (hence, use 0 or nothing as delay).
