Steps to reproduce

If you enable strict in tsconfig - compiler will throw "overload" errors, when you disable it - mapState works, but then methods will throw "Property 'xxx' does not exist on type 'Vue3Instance" error. As we tested "under the hood" strictFunctionTypes causes these errors.

Versions: node: v14.19.1 npm: 6.14.16

strict = false (method)

strict = true (mapState)

What is expected?

mapState would work without errors when strict is enabled.

What is actually happening?

It throws ts errors.
