IPython 8 changes terminal cursor

After starting IPython 8.0 and then returning to terminal, the cursor changes from block to I-Beam.

Before:

After:

I need to call reset to get the cursor back to block.

Setup: XFCE terminal + zsh + starship

Personally, I’d strongly prefer that IPython do nothing whatsoever with the cursor. Even when IPython changes and then restores the cursor as expected, it’s still unexpected. No other terminal application I use forcefully modifies the cursor – not even Vim or zsh. I’d prefer that IPython behave like (almost) everything else in the POSIX ecosystem. Is there a trivial way for end users to disable this questionable functionality without manually modifying IPython source?

If I grok this comment from @jonathanslenders above correctly, the only means of disabling IPython’s cursor modification at the moment is to forcefully pass either cursor_shape_config=None or cursor_shape_config=prompt_toolkit.cursor_shapes.CursorShape.BLOCK to the PromptSession in IPython/terminal/interactiveshell.py. Is that right?

If so, that’s better than nothing; at least I have some recourse. Still, changing the cursor without the user’s permission only disgruntles users. This should ideally be an opt-in option disabled by default.

If you’d like to make this configurable, I’d be happy to accept a PR that adds the option. Just make sure to take other PRs that are currently open into account, specifically those open by @jonathanslenders.
