Describe the bug

I have a responsive dashboard, which allows users to add/remove widgets as well. I am saving the layouts in db.

When md breakpoint is active, I add a new item ( by just pushing a div with key and data-grid prop on it ), the onLayoutChange gets triggered I save the values of the second arg in db ( i.e. all layouts keyed by breakpoints )

However, when I start to increase the screen size, the newly added item shrinks because for bigger breakpoint the layout is not defined.

If we try the opposite, i.e. add a new item in the xl mode and then reduce the screen size everything works fine.

Your Example Website or App

https://codesandbox.io/p/sandbox/g6npg3

Steps to Reproduce the Bug or Issue

the example attached do not add/remove items but simulates the same problem. the layout for "2" is defined in md so it breaks in the lg.

  1. codesandbox -> https://codesandbox.io/p/sandbox/g6npg3
  2. increase/decrease the preview pane size

Expected behavior

it should either remain the same size or increase but definitely not shrink.

implemented a custom solution to generate the layout in all breakpoints.

const getLayoutForNewItem = ({
  inputParam,
  currentLayouts,
  currentCols,
}: {
  inputParam: NewItemInputParams;
  currentLayouts?: Layout[];
  currentCols: number;
}) => {
  const { key, width = 6, height = 6 } = inputParam;
  const _defaultReturn = {
    x: 0,
    y: 0,
    w: Math.min(width, currentCols),
    h: height,
    i: key,
  };

  const sortedLayout = currentLayouts?.sort((a, b) => {
    if (b.y !== a.y) {
      return b.y - a.y;
    }
    return b.x - a.x;
  });

  const _lastItem = sortedLayout?.[0];

  if (_lastItem && currentCols) {
    const leftX = _lastItem.x + _lastItem.w;
    const rightX = leftX + width;
    if (rightX > currentCols) {
      return { ..._defaultReturn, y: _lastItem.y + _lastItem.h };
    }
    return {
      i: key,
      w: width,
      x: leftX,
      y: _lastItem.y,
      h: height,
    };
  }
  return _defaultReturn;
};

this can be called for each breakpoint.
