I am facing an an usual issue while working on TreeGrid Panel on IE11.

After Tree is rendered, After Expanding the Node, the expand icon (+) turns to collapsed icon (No issues as of now). As soon as I move my mouse to any other row in the grid, the Collapsed (-) icon turns to Expand (+) icon automatically even though the node remains in collapsed state.

This occurs only while I move my mouse out of the Current row which corresponds to any Node. If I keep my mouse pointed to the node, it retain the after expand icon (-) .

This behavior was observed on IE10 and IE11. It works good on IE8 and FF.
