Steps to Reproduce

The validation layout breaks if a long field name appears in the preview. The resulting problem goes higher than the preview - no scrollbar appears and part of the view (including action buttons) are out of the screen.

Expected Results

Limit the preview width - overflow can be scrolled. The width of preview content shouldn't affect rest of the layout.

Actual Results
