Describe the issue:

Can't go back to a single editor cursor from multiple cursors.

Steps to reproduce the issue:

1. Open a Positron notebook
2. Type hello hello into a cell editor
3. Select the first hello and press Cmd+D
4. Verify that both hellos are selected - PASS
5. Press escape
6. Verify that we're still in edit mode and the single cursor was restored - FAIL

Expected or desired behavior:

The escape should be swallowed by the editor and we should remain in edit mode with a single cursor.

Were there any error messages in the UI, Output panel, or Developer Tools console?

No.
