Description

In a .NET 9 Web API app (and also a stand alone .NET 9 web app).

When using the Companion app to preview a PDF from QuestPDF, after calling doc.ShowInCompanion(); the calling application will be paused on that call, waiting for the Companion app to return.

This makes using the Companion difficult at best, as I need to stop and re-run my app to get control back.

Execution will pause at the doc.ShowInCompanion(); statement and never return. The following Console.WriteLine statement will never execute.

Research direction

Reproduce the issue from a .NET 9 Web API or standalone web app by calling doc.ShowInCompanion(), then observe whether the following Console.WriteLine executes. Trace the Companion app's handling of that call and consider the return path; done means control returns to the calling application without needing to stop and rerun it.
