the class DiffTest method test_TDP_1184.

/**
 * After TDP-1184 fix, there is a problem on preview (regression?).
 * Use case is:
 * - delete a column (lastname here)
 * - add new columns (with split on city here)
 * - preview an action on the first new column (uppercase on 0000 here)
 * <p>
 * -> lastname is still on the preview data for lines 4 & 6. it is absent (which is what we expect) only for the first line!
