Issue with People Picker fields not showing in browser form web part with URL parameters

I am having an issue with person / group picker fields in an InfoPath 2010 browser form, that I hope somebody can assist with.

Background:

I have a SharePoint 2010 list, on which I have used the 'Customize form' feature to modify the default form through InfoPath.
I then have an InfoPath form web part on a page, where I want the data displayed in the form to be based on an ID parameter passed via the page URL. I have achieved this using a simple query string (URL) web part on the same page. This works by:

Through the Manage Web Part Connections in SharePoint Designer, set the value of a new hidden field 'ID_LookupFromURL'.
In the form template, I have a rule that runs when the 'ID_LookupFromURL' field changes, it sets the ID query field to the same value, and looks up the data from the main data connection, which is then displayed on the form.

Issue:

This entire process is working almost perfectly at the moment, but the only problem is that any people picker fields on the form are hidden when the form first loads. This does not happen if I load the form normally without passing a URL parameter. It is as if there is an extra delay with processing the people picker values, and when I use this extra step in pre-loading the form through the URL parameter, it interferes with the process which shows the people pickers.

When filling out the form, if I change any field that requires a lookup to another data connection (anything that requires the form to send information back to the server or lookup information from the server), only then will the people picker field show.

Any ideas on what may be causing this issue?
