After variable row height has been set for a JTable (by calling the
JTable.setRowHeight(int, int) method), a bug in JTable.tableChanged
event handler prevents the number of rows displayed by the table to
increase when model fires TableStructureChanged or TableDataChanged
events; the number of rows can shrink if the new data contains less
rows; TableRowsInserted event is still handled correctly.

    // bug does not show when the following line is commented out
