UI Shaking When Dragging Grid with Larger or Equal Height into Another Grid

[rolandsoh96]

Description:
I am encountering a UI issue with Gridstack when dragging a grid into another grid. If the height of the dragged grid is greater than or equal to the height of the dropped grid, the UI begins to shake uncontrollably when the dragged grid is close to the dropped grid.

Steps to Reproduce:

1. Create two grids, one with a height greater than or equal to the other (e.g., draggedGridHeight >= droppedGridHeight).
2. Initiate a drag operation on the larger grid.
3. Drag it close to the smaller grid.
4. Observe the rapid shaking of the UI.

Expected Behavior:
The grids should align smoothly without any shaking, regardless of their relative heights.

Actual Behavior:
The UI shakes uncontrollably when the dragged grid is close to the dropped grid.
