IE8: tree column resize fail

Good Day!

I have observed a strange situation during tree column resizing:

  1. Decrease browser window until tree horizontal scrool bar appears
  2. Scroll to the last column
  3. Try to decrease the column width
  4. You can see something likes the attached - the column header position does not relate with the column position (It is shown with the red lines).

Also I want to say that Refresh (F5) restores the normal state.
