Hello Anton, yes sorry for the late response, I had some personal problems, it's in order ;-)
I did not apply 906 correcting but if I understand correctly it concerns just "When it is private, then profile link is not working, it would be better some popup when profile link is clicked. "

You tell me, it's fixed by ticket 906, okay.

But if you look closely at this video there are still on other problem.

Looks like "View Person Profile" disabled in the permissions only acts on two profile, in fact, both profiles or the avatar is hidden.
For all other profiles, or the avatar is visible, I can still see all the details even if "View Person Profile" is disabled (for the non-member level).
As I said above, Vincent M had exactly the same problem, at home too, "View person profile" is disabled (for the non-member level), masked the avatars of only two accounts, all the others were visitable .
Perhaps you would have easier to observe this phenomenon directly on my site? If you want I give you access.
