Resizing the last column in a table using the right most handle causes
property change events to be sent on the width of the column even if
the column width does not change visualy.

You can see that events are sent using addPropertyChangeListener()
on the last column and listening to "width" changes.

To reproduce:

- Try resizing the last column using the right most handle.
- If you attempt to resize the frame after that, the column instantly
  colapses to a different size.

Impact:

We cannot reliably determine the width of the column.
