XamDataCards disable horizontal scrollbar if fields larger than view


I am using XamDataCards to display a single column of cards. The layout of my card is like that in the Custom Card Layout sample in that I have a picture in column 0 row 0 and a number of text fields in column 1. One of the text fields in column 1 exceeds the length of the card and the field that has the image starts off larger than required, so I am setting Width="Auto" in my field settings which is reducing the image field to be just slightly larger than the image and expands column 1 to the length of the large field. The problem is this results in a horizontal scrollbar to appear on the cards which I do not want. I just want the content of the field to be cut at the edge of the card.

How do I disable the horizontal scroll bar from appearing?
