Hidden Field Magic String [@Url] doesn't work on a paged form

[OwainWilliams]

If a hidden field is added to a form which has multiple pages, the magic string [@url] only works if it's on the first page of the form.

This field is on the second page of a form:

If I move the field to the first page you can see that the value is populated as expected.

Reproduction

Great a form with multiple pages on it.
Add a hidden field question to the second page and use a magic string

Look in the rendered form on the front end and the value will be [@url] rather than the page url.

Move that field to the first page of the form and view the source again, you'll see the value is correct and it shows the url as expected.
