Multiline editing still broken

Multiline editing was discussed 3 years ago in this Issue already (https://github.com/gregsexton/ob-ipython/issues/79). However it seems there has not yet been any progress on this as I still observe the issue that when I open the ipython repl from within a ob-ipython code block ( C-c C-v C-z), and try to enter a multiline command like

if True:
print('works')

after the hitting enter the first time, it directly complains with

> In [47]: if True:
> File "", line 1
> if True:
> ^
> SyntaxError: unexpected EOF while parsing

Is there a workaround or a planned solution for this?
