BUG: resize specific axes 'x' does not work (grid crashes)

[timothymarois]

Entire grid falls apart and everything is squished at the top if using resize axes: 'x' with the following options:

               widget_selector: 'li',
                widget_base_dimensions: ['auto', 110],
                autogenerate_stylesheet: true,
                avoid_overlapped_widgets : true,
                min_cols: 1,
                max_cols: 14,
                widget_margins: [5, 5],
                shift_widgets_up: false,
                shift_larger_widgets_down: false,
                move_widgets_down_only: false,
                scroll_container : '.app-main',
                resize: {
                    enabled: true,
                    axes: 'x'
                },
                collision: {
                    wait_for_mouseup: false
                },
