Version: 5.10.1

Configuration

setup.cfg (no other configs):

[isort]
profile = black
ensure_newline_before_comments = false
line_length = 80
sections = FUTURE,STDLIB,THIRDPARTY,FIRSTPARTY,LOCALFOLDER

I assume that profile setting overwrites ensure_newline_before_comments OR the later one is not working at all somewhy OR I do not understand it right.

Reproduce the report with isort 5.10.1 using the shown setup.cfg, including profile = black and ensure_newline_before_comments = false, against imports containing a commented import block. Start by tracing how these options are loaded and applied, then verify that the configured behavior produces no formatting error for the supplied example.
