Scope Disposed Error in V4 Functions

I'm having an issue similar to #7874. I've attached a Visual Studio project with a minimal reproduction. The issue occurs when a service registered as a singleton accepts a dependency Func\ where Service is registered as scoped or transient. Similar to #7874, the first request is successful, but the second request errors with the error "Scope disposed{no name} is disposed and scoped instances are disposed and no longer available.".

To reproduce, open the solution from the attached zip, run the function app, and make 2 requests to http://localhost:7071/api/Function1

Open the attached V4BugRepro.zip in Visual Studio, run the function app, and reproduce the problem by making two requests to http://localhost:7071/api/Function1. Compare the singleton's Func dependency with the scoped or transient Service registration and trace when the scope is disposed. Done means the second request completes without the scope-disposed error.
