This issue is similar to this comment

Another one is

print(
'%s'
% 'foo'
)

which gets transformed to

print(
    "%s"
    # %# 'foo'
)

But yeah, if black accept https://github.com/psf/black/pull/2357 then, jupyterlab_code_formatter could just call black.format_cell and this and the other similar issues would be solved

https://github.com/psf/black/pull/2357 has been merged, so if/when they make a new release then this issue will be easily addressable
