Bug Report

Reproduction of the problem

1. Visit the Spreadsheet Server Import/Export live demo.
2. Import the attached example(FrozenPaneExample.zip).

Current Behavior

The imported xlsx file appears to overflow the Kendo UI Spreadsheet component.  See screencast(SpreadhsheetOverflowFrozenPane.zip)

Expected Behavior

Workaround

Reduce the amount of frozen rows/columns to fit into the widget.
