Polish interactive window

[joyceerhl]

We shipped a native interactive window experience in the July release. This issue tracks polishing the interactive window experience.

Done

• Variable explorer should be populated when focus is in script file Variables explorer not updating when running the interactive session from the editor #6993
• Fix interrupt/restart Restart kernel on Python interactive window does not actually restart kernel #7081
• Provide some solution for esc and ctrl+u clearing the interactive window input box Esc and Ctrl+U no longer clear the contents of the interactive window input box  #7157
• Context keys are not correctly set Command palette interrupt/restart not there for a python file #7158
• Support or deprecate missing settings Add back support for jupyter.collapseCellInputCodeByDefault setting in interactive window #7031, Review all settings, commands, activation events in package.json #7094
• Execution count incorrect Running code from the interactive window input box causes ipython-input temp file to open for debugging #7156
• Code dedented on IW export Interactive Window -> Save to notebook, loses code formatting.  #7088
• No execution time set Cells submitted to the interactive window from a Python script don't have timer in the cell status bar #7162
• Jupyter won't select specified virtual environment on first start #7013
• Support for Remote in IW window #6881
• Jupyter interactive: run current cell throws IndentationError: unexpected indent #7303
• Delete cell usability:
  Jupyter Interactive | Delete Cells without expanding it (July update issue) | Asking for roll back #7188, Bring back remove cell button to the left of each cell #7250, Native Interactive - Shouldn't have to give focus to cell to delete it from IW #6475
• Changing the kernel doesn't work for Interactive #7288
• Interrupt button is enabled even when there's no code running in interactive window #7269
• Clicking 'Change Kernel' for interactive window started from script file does nothing #7476
• Debugging cells in the interactive window will show the 'temp hashed file' if you restart the kernel #7366
• Output order is incorrect #7280

Upstream

• Interactive window interactive.history.previous and interactive.history.next do not persist history position when reexecuting commands vscode#131659
• New interactive window doesn't show execution count when collapsed vscode#132064

Deferred

• Rework command queuing Rework command listener for interactive window #7164, https://github.com/microsoft/vscode/issues/130295

Not sure if you want separate issue for this, but one helpful minor tweak would be to show the spinner/completion checkbox regardless of the number of lines of the input cell. Currently, when I send multiple cells to the interactive window at once (from a cell-delimited (#%%) script file), then each execution cell is displayed collapsed in the interactive windows. This makes it very difficult to tell whether execution has completed -- have to expand each cell to see the spinner/checkbox.

Thanks for this helpful list @joyceerhl. Should #7065 also be included here?

[joyceerhl]

@ihnorton In the current Insiders build and upcoming Stable release, we will display a blue progress bar above each cell that is executing--this is the same progress bar that is displayed when the cell is expanded, and @rebornix pushed a change to ensure that the progress bar is also displayed when the cell is collapsed. Hopefully that is a slight improvement for now.

@thor4 #7065 was an existing issue with the variable explorer for native notebooks so should be addressed outside of this issue, which tracks interactive window-specific issues.

Will tackle https://github.com/microsoft/vscode/issues/130295 at the start of next iteration as it involves a somewhat risky refactor. All remaining issues are either upstream (discussing solutions with @rebornix) or fixed in Insiders.
