Dialog deletes Form Elements

[bht]

Please refer to the attached testcase.

A script cannot access a form element if the dialog is contained in the form that contains the form element.

The script can access the form element if the form is entirely contained in the dialog.

This is relevant in cases where the form contains multiple dialogs, each of which has to deal with separate form elements, but the form has to be submitted as a whole.

Obviously there is a workaround, using multiple forms, but this doesn't seem right to me.

Yes, this is a limitation of how Dialogs work. Dup of #3300.
