Bug description
If multiline text is copied in to a markdown cell (on Windows), the copy/paste produces line endings of \r\n. With further editing of the markdown, sometimes the \r and \n can become separated and then cause very strange formatting effects.
How to reproduce
Open a fresh python 3 notebook in tlhj
create a cell, change type to markdown
Open a blank document in Notepad on windows
enter four lines: Line 1 Line 2 Line 3 Line 4
Then select all lines with CTRL-A, copy with CTRL-C
Paste into the markdown cell with CTRL-V
Position cursor after the 2, and use the delete key to put Line 2 and Line 3 on the same line.
Use Shift-Enter to format the text.
Notice that the 2 is missing, even though if you double click to edit the markdown, it remains present.
Some really strange things can then happen with further editing of these lines, where bits of text get moved around to the wrong line or disappear altogether. If you save the notebook and then revert to the saved version, the errors become permanent.
Expected behaviour
Was expecting output of: Line 1 Line 2 Line 3 Line 4
Actual behaviour
Found: Line 1 Line Line 3 Line 4

``` # paste relevant logs here, if any I don't see any log messages that look related. The only ones that seem even remotely possibly relevant are: Oct 18 14:10:40 xxx.xxx.xxx jupyterhub-singleuser[360391]: [W 2023-10-18 14:10:40.609 JupyterNotebookApp] 'extra_template_paths' was found in both NotebookApp and ServerApp. This is likely a recent change. This config will only be set in NotebookApp. Please check if you should also config these traits in ServerApp for your purpose. Oct 18 14:10:40 xxx.xxx.xxx jupyterhub-singleuser[360391]: [W 2023-10-18 14:10:40.521 ServerApp] A `_jupyter_server_extension_points` function was not found in notebook_shim. Instead, a `_jupyter_server_extension_paths` function was found and will be used for now. This function name will be deprecated in future releases of Jupyter Server. ```
