autoAdjustColumn does not work for the tree in TreeGrid

Hi,

When having a TreeGrid, which of course has a tree type column, that column size is truncated when trying to auto-adjust.
Tested on Win7x64 Chrome & IE9.

Case opened.

Unfortunately the issue cannot be reconstructed locally.
adjustColumnSize() method works well for us with tree column in IE9 and Chrome.
If issue still occurs - please, provide any kind of sample
