Has "chmod: changing permissions of '/XXX': Bad address" been fixed in QuTS hero h6?

“chmod: changing permissions of ‘/XXX’: Bad address” has been a problem for a long time in docker on qnap. There is several issues as well as qnap faq.

There is some reports that this should have been fixed, though I cannot find anything concrete. Since I am unable to test myself since I do not have a testlab, could Qnap staff please confirm if this has been fixed in QuTS hero h6?
