TypeScript: Excessive stack depth comparing generic preloadedState with DeepPartial

See original GitHub issue

Do you want to request a feature or report a bug? Bug

What is the current behavior? Passing a generically typed preloadedState parameter into createStore creates an “Excessive stack depth” error in TypeScript due to the comparison between S and DeepPartial<S>

Sandbox: https://codesandbox.io/s/busy-leavitt-wrpnx?fontsize=14

More information at https://github.com/Microsoft/TypeScript/issues/21592#issuecomment-503837592 - this is caused by a TypeScript bug, but the TypeScript devs have suggested that Redux may not actually need to be using the DeepPartial type here.

What is the expected behavior? No TypeScript errors

Which versions of Redux, and which browser and OS are affected by this issue? Did this work in previous versions of Redux? In theory this affects any version of Redux using the DeepPartial type. The symptoms and workaround have changed in recent versions of TypeScript; I’ve reproduced the issue with typescript@3.1.6 and typescript@3.5.1
