Retain formula references in PALO.ESELECT after using element picker

When a user clicks on a Web spreadsheet cell which contains a PALO.ESELECT function, this will open an Element Picker dialog on the dimension where the user can then select some other element.

If cell references, or named ranges are used in the function (especially for the connection/database argument) this will be replaced with a string after user makes a selection in the dialog. It would be better if such references would be retained.
