Reproducer:

function demo_5($target) {
  var sequence = Array.from(Array(5).keys());
  var matrix = Caleydo.d3.parser.parseMatrix(
      // times table
      sequence.map(function(m){
        return sequence.map(function(n){
          return m*n;
        })
      }),
      sequence, // row_ids
      sequence // col_ids
  );

  var minus_one = Caleydo.core.range.parse('0:-1, 0:-1');
  var minus_one_view = matrix.view(minus_one);
  Caleydo.core.multiform.create(minus_one_view, $target[0]);

  /*
  Behaves as expected:
    ID  0   1   2   3   4
    0   0   0   0   0   0
    1   0   1   2   3   4
    2   0   2   4   6   8
    3   0   3   6   9   12
    4   0   4   8   12  16
   */

  var minus_two = Caleydo.core.range.parse('-3:-1, -3:-1');
  var minus_two_view = matrix.view(minus_two);
  Caleydo.core.multiform.create(minus_two_view, $target[0]);

  /*

  But expected:
