getPreferredSize() is called from ToolTipManager but it is done *before 
*calling Tooltip.show() which actually triggers PropertyChangeEvent with 
"graphicsConfiguration" property.

Now, View is updated by calling BasicHTML.updateRenderer() when 
"graphicsConfiguration" property is fired to notify transform is 
changed, so during preferredSize() call, the View has not yet been 
updated with correct transform.

So, my proposed fix is still same
