Could not find the drag and drop manager in the context of RootDropTargetsComponent

[zqqqqz2000]

when I install mosaic using npm i react-mosaic-component, npm shows a lot of warnings about resolve dependency(include dnd). then I run the demo, error below:
Could not find the drag and drop manager in the context of RootDropTargetsComponent. Make sure to render a DndProvider component in your top-level component. Read more: http://react-dnd.github.io/react-dnd/docs/troubleshooting#could-not-find-the-drag-and-drop-manager-in-the-context

Had similiar issue, the reason why it works with yarn and not npm currently is that yarn by default won't install peerDependencies but npm 7+ does. It seems like some peerDeps are breaking the setup - haven't chance time to inspect what exactly causes the problem but when installed with --legacy-per-deeps flag which skips peerDependencies, everything works.

This is now fixed in v5.2.2
