TextBlock MouseEvent doesn't work properly when text alignment is applied.

When I have textblock with TextAlignment.Center
TextBlock's MouseEvent triggers as if text is aligned to left.

For example, string TextBlock with large width like below,

       "                centered               "
        XXXXXXXX00000000000000000000000000000000          Where X is mouse detected area, 0 is not.

When I move mouse over "XXXXXXXX" area, MouseMove, Enter, Leave event fires  
but no events fires when move over "00000000000000000000000000000000" area.
