I've created a panel contained in the 'east' zone of a border layout viewport which contains vertically stacked input fields with the bottom field being a textareafield.
What I want, is the textareafield to resize with the viewport but maintain a minimim vertical height.
I have set the overflowY on the form to 'auto' to display a vertical scroll bar if the viewport is smaller than the form.

The problem is by the time the vertical scrollbar is displayed the textareafield has already been reduced in height to 0 pixels so you can't read or edit it's contents.

Is there any way to fix this?
