[FIX] strange draggable behavior in Chrome 15/Linux

dragging any other row than the first one in a sortable table (table with sequences)
has the row going way to the right of the table, in both editable list views (e.g.
tasks) and relational fields (e.g. Accounting > Configuration > Financial Accounting
> Taxes > Taxes[form] > Child Tax Accounts
