Issue using blazor virtualize component with FluentMediator

Hi guys,

I'm using FluentMediator in two of my projects.
Last days I found an issue in my app where my requests get an OperationCancelledException.
After a few hours trying to resolve, I found it on my Windows Event Viewers.
It's looks like the FluentMediator crashing between my controller and my use case class.
Can you guys check it out?

_`at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context)

Start with CancellablePipelineAsync.Pipeline.PublishAsync and the stack trace's UsersController.Get at line 43 to determine where the cancellation originates when using the Blazor Virtualize component. Reproduce the OperationCanceledException and trace the request through FluentMediator; done means the request no longer fails unexpectedly, with a regression test covering the scenario.
