Title: "TypeError: Cannot read property 'setState' of null" when using React.lazy
Description:
When using React.lazy to lazily load a component, users are reporting a "TypeError: Cannot read property 'setState' of null" error in certain scenarios. This issue seems to occur when a lazily loaded component is unmounted before it finishes loading, leading to a null state and the error.
Expected Behavior:
The lazy component should load without any errors, even if it's unmounted before it finishes loading.
Actual Behavior:
A "TypeError: Cannot read property 'setState' of null" error is thrown in the console, and the lazy component fails to load properly.
Possible Solution:
A potential solution could involve modifying the React.lazy implementation to check if the component instance still exists before attempting to set its state during the loading process.
Please let me know if you need any additional information or have any suggestions for addressing this issue.
