Hi.

I'm wondering if it is possible to adjust the width of a UIHint.Textarea in a PropertyType editor easily (hopefully no dojo/custom editor :))

I've made a PropertyList of a custom type in a block:

[EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor))]
public virtual IList TextLinesTwo { get; set; }

And in my AdditionalProductLine class I have a string property with a UIHint.Textarea:

[UIHint(UIHint.Textarea)]
public string AdditionalProductLineReadMore { get; set;  }

And it seems to work fine, however when I open the editor the text area is too large for the box and causes usability issues. I would love it if I could somehow control the width of a textarea if opening via the property editor, however I cannot seem to find a way to do it.
I tried simply creating an editor descriptor that added a width style for my specific property, but that just seemed to remove the list entirely.

( metadata.EditorConfiguration.Add("style", "width: 100px");)
