Review comment:
Unfortunately the Python SDK interprets an element that's a WindowedValue as
an element that should have its windowing information changed. This is used
directly by the ReverseTestStream to produce WindowedValue args that keep the
windowing information. But if these elements were WindowedValues themselves,
then the Python SDK would reinterpret and unnest them at every step.

> This issue tracks the work items to introduce streaming support to the
> Interactive Beam experience. This will allow users to:
> * Write and run a streaming job in IPython
> * Automatically cache records from unbounded sources
> * Add a replay experience that replays all cached records to simulate the
> original pipeline execution
> * Add controls to play/pause/stop/step individual elements from the cached
> records
> * Add ability to inspect/visualize unbounded PCollections
