Autosize a text field on a form

Has anyone found a way to set a text field in a form so that it autosizes vertically to the content? I want to have the form display the full content of fields when it opens and adjust itself as data is either added or taken away. I’ve read that there is a new value (‘content’) available to the CSS property ‘field-sizing’ that is available in more recent browsers. Is there any way to accomplish autosizing of fields in Scriptcase?
