Expandable text fields-why does it break across pages when there is no text pushing it down?

I have a number of fields that are expandable on a 7 page form.  Is there a way to prevent the text field from breaking across two pages if there is not enough text in it that pushed it down to the next page?  If the text field only contains one or two lines, but the field can handle 5 before it expands; is there a way to prevent it from breaking across the row, but have it stay intact and go to the top of the next page instead of breaking across two pages?
