The problem is *not* fixed. I was the one who reported this problem two years ago. I did the same notmuch search again. Since I did no know if it's important with which version the emails were indexed I did a full index with notmuch 0.17+40~gecbb29e. I still have the mbox produced with notmuch show two years ago. Viewed with mutt (1) I see 206 messages in 7 threads (number of lines after collapse-all) (notmuch emacs show showed three threads then). One of the threads is the one I searched for. Today I produced another mbox with the very same command but with a now larger email corpus freshly indexed with a fresh notmuch. The mbox contains (according to mutt) 507 messages in 34 threads. One of them is the thread I searched for. I grepped for the 7 subjects within the 34 subjects and only 5 showed up. Only 17 of the 507 messages arrived since the problem report two years ago. If somebody want's to dig into this: I can provide the two mboxes. Disclaimer: Many of the emails which arrived before the problem report are not the exact same than then, because since the I mangled them with a script. This should have not changed the threading but I cannot be 100% sure. But if it's important for further investigation I'm probably able to reproduce the status quo of the email corpus then from my backups. Thanks for your persistence.
