Parcel never mounts component with StrictMode enabled

[eljo]

With React 18 development library and <React.StrictMode> the component does not mount the actual parcel.

Observed flow:

• componentDidMount is called which calls addThingToDo
• componentWillUnmount is called which calls addThingToDo and immediately sets this.unmounted = true
• First addThingToDo is invoked and immediately returns as this.unmounted is true.

Hi, did you solve the problem?

I just stumbled upon this same scenario.

We experience the same issue.
We use the Parcel component and what I noticed is that it mounts it, it's visible for a split of a second and then it unmounts it.
Could it be that in the second render of StrictMode the parcel is considered mounted? Some timing issue maybe?
I hope you can figure it out soon.
