"WeakMap key undefined must be an object" on deleting an item from the collection

[zspitz]

Describe the bug
I have a collection of items which I pass into Masonry. When I delete an item, recreate the collection, and thus rerender the component holding the Masonry, I get "WeakMap key undefined must be an object".

To Reproduce

1. Go to the appropriate route/component (loader loads the items, Masonry loads successfully)
2. Click on the delete button of the item (asynchronously, item is POST-ed to the relevant route, which reruns the loader, returning a new collection)
3. The error appears

Expected behavior
The component should render successfully.

Screenshots

Desktop (please complete the following information):

• OS: Windows
• Browser Firefox / Chrome
• Version Firefox 130.0 / 128.0.6613.138

(not tested)

Additional context
(May or may not be relevant.) The collection is retrieved by a React Router Ioader into the component via the useLoaderData hook; i.e. not some internal state.

I delete the item using an async function; POST-ing to the React Route of the component and thus triggering the loader to run again, and the component to re-render.
