When dragging a grid item downwards in a grid, an infinite number of
rows can be added. This is unconvenient because it is difficult to
escape a grid if the snippet is "container-fluid" for example.
This commit limits the number of rows that can be added at once when
dragging downwards. The limit is fixed to 10 rows. Of course, it is not
a total limit, this means that after dropping, if the grid item is
dragged again, 10 additional rows can be added.
