* Here we have to reset the ref to null because in StrictMode, the effect will run twice,
* but it will keep the same ref value from the first render.
*
* In browser, React will clear the ref after the first effect cleanup,
* so that wouldn't be an issue.
*
* In StrictMode, however, the ref is kept,
* and in the hook above the code checks for `prevPropsRef.current === null`
* which would be false so it would not dispatch the `addCartesianGraphicalItem` action again.
