Description
For use cases such as progress bar output, we don't see the progressive ANSI control characters, as ipykernel buffers output and sends the final state of the output instead.
We need to investigate ipykernel as to whether we can get it to stream output instead.

Research direction
Start by reproducing the alive_progress progress-bar case in Positron and inspect how ipykernel buffers and sends output. Determine whether progressive ANSI control characters can be streamed instead of only the final state, then verify the bar updates incrementally in the affected Python output flow.
