-RM-277-MR-Custom Widgets cannot be horizontally shrinked right after start.
When starting OW with a dataset applicable to histogramView module, the custom widget of the histrogramView cannot be shrinked. However if you put it outside the main window, it can be resized seamlessly. After inserting it back into OW main window, resizing remains possible. Maybe some initialization issue.
