Datagridview scrolling bug? due to invisible row's height adjust

[Guest]

I have a datagridview, setting its datasource to a dataview which is over an
datatable in memory. no filtering rules applied on dataview/datatable.

AutoGenerateColumns = false;
AllowUserToAddRows = false;
EditMode = DataGridViewEditMode.EditProgrammatically;
MultiSelect = false;
AutoSize = true;
SelectionMode = DataGridViewSelectionMode.FullRowSelect;
RowHeadersVisible = false;
AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders;
AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
ColumnHeadersHeightSizeMode =
DataGridViewColumnHeadersHeightSizeMode.DisableResizing;
ColumnHeadersDefaultCellStyle.WrapMode = DataGridViewTriState.False;
DefaultCellStyle.WrapMode = DataGridViewTriState.True;
RowsDefaultCellStyle.WrapMode = DataGridViewTriState.True;

The problem is:
Assume displaying area can display 10 rows, and I having 30 rows, row 10 has
a cell value which is too long and will be wrapped. this row's height will be
bigger than normal. I select this row, then scroll further down until this
row scroll up till invisible. Now click a button to edit the corresponding
value of that cell in the datatable such that it is short and no more
wordwrap. Since AutoSizeRowsMode applies to all cells, the row contain that
cell will be updated with a smaller height. Then scroll up till top,
Exception comes out:

Now try to resize the datagrid , then this problem disappears.
Looks like when a row's height is adjusted while it is not displayed, the
scrollbar value is not updated. Feel like a bug. Any idea? Thanks in advance.
