Description

If the cursor is on the last line of the current cell in a .py file, saving will cause the cursor to automatically wrap to a new line. This leads to the cursor constantly jumping to a new line while I'm writing code if I have autosave enabled at a higher frequency. The only workaround is to manually insert a blank line at the end of the cell before starting to write.

Contributor guide

Research direction
Investigate the save event handling in the extension and identify why the cursor position is being modified on save when it's on the last line of a cell. Look for any cursor management logic triggered by document save.
