Grid not extending properly when adding new widgets

[Bajena]

In my project I have a feed-like grid that:

• supports dragging and dropping new widgets on the grid - widget is added at the bottom of the grid
• can extend vertically, but not horizontally when adding new widgets
• Allows saving the grid details in the backend
• Uses following options:
  max_cols: 6, min_cols: 6, autogenerate_stylesheet: true, widget_base_dimensions: [40, 40], widget_margins: [4, 4]

The grid is not extending vertically after performing following steps:

1. Add enough widgets to fill the grid vertically
2. Save the grid
3. Refresh the page - gridster reloads the grid with previously saved config
4. Try adding a new widget - it's added, but the grid does not extend properly, so the new widget can't be manipulated.

It's important to note that this issue does not occur when adding widgets to a "fresh" grid.
