Question about Ext.resizer.BorderSplitterTracker.
A have some panels and containers in ViewPort. They are devided with splitter.

If start drag any splitter and press mouse while first loading data on any container, and release the mouse after container data load, then event "dragend" of Ext.resizer.BorderSplitterTracker not correctly finished. Property "active" of Ext.resizer.BorderSplitterTracker is true. I call manually method endDrag() of element Ext.resizer.BorderSplitterTracker and then "active" property setted false.
But, if i moving mouse over ViewPort items, tracker also move. Because, in window.document stayed any "mousemove" event listener, wich the move BorderSplitterTracker element.

How can i solve this problem?
