Description
This PR introduces a
clearOutputs()method to theISharedCodeCellinterface and its implementation inYCodeCell. This method provides a clean and direct way to remove all outputs from a code cell in the shared model.This change is motivated by a bug in JupyterLab where uncoalesced stream outputs can persist in the cell output area. The root cause is that the frontend coalesces outputs, but the shared model retains multiple entries, making it tricky to clear all outputs using
updateOutputs()when their lengths differ.
