Clear synchronization context in to task()#1774
Merged

Conversation
UI frameworks (WinForms/WPF/Avalonia) install a SynchronizationContext on the test thread. Without a running message pump, async IO in Verify's pipeline would post continuations to that context and deadlock. Clearing it synchronously in ToTask() before the pipeline starts prevents the capture. Adds a test that reproduces the scenario using a recording context.
