Shift + enter from interactive Python pane sends command to terminal

When working in the interactive window, despite the fact that the tip tool says “Press shift + enter to execute”, doing so sends the command to the terminal instead of running it in the interactive window. Normally I would consider this a bug with the Python or Jupyter extensions, but it behaves normally in VSCode, which suggests Cursor is causing the bug. Is there a setting that’s been changed on our behalf?
