Any developper can repro the bug easily: create a Gmail account (they
are now free, and don't need sponsorship anymore; beta have been close,
and official product have been launched years ago), configure two
different Thunderbird profiles to access the same Gmail account, send
one email from one box to the other one, read the mail on both, mark the
mail as unread on one, and click GET MAIL on the other one, you will see
that email is marked unread only after restarting "the other one".

You don't need huge amount of data from users, strace or backtraces. Any
dev can produce desired amount of logs for free, any time, and from any
country (yes ... I had country specific issues with Google in the past -
this bug is NOT one of them). To dig deeply into client-server
communication, tcpdump often helps.

Thunderbird is a free software. And dev always remind users that they
are volunteers. But the products of the Mozilla fundations have a
reputation to defend; they slowly became popular, and are now used by
many people ... not only geeks in the cave using Linux for religious
reasons; Thunderbird is used by people why have serious work, and who
consider Thunderbird as a work tool. This means ... the tool must meet
minimal requirements, and must work at least, as good as other
concurrent products. And since mid 2013, thunderbird have serious
issues. It does not sync properly messages status, and does not work at
all anymore with Google Calendar (yes I know, it's not Mozilla Fundation
who was responsible for Google Calendar Exchange server shut down; but
the moz team could have worked on making TB compatible with an other
protocol). Now, TB have become a poor mail reader not even able to track
a READ STATUS, I can not use PGP encryption at all (since TB3, or maybe
even TB2, I forgot), and it can not let me use my calendar any more. I
wonder why I have not yet changed MUA.

Dev always claim that ... they work for free, and are free to choose
what to work on, which snipset of code they want to have fun with. By
letting users down on basic features, users will get bored of the
product. This bug is one of the few that I consider critical and urgent.
Last week I was trying to configure an old Nokia Symbian S60 for Gmail
sync; in my research, I have found several articles saying that Gmail
closed the Exchange access, and that Mail for Exchange for Symbian is
now deprecated because of Google choices; the articles was also doing an
overview of other affected products; MFE at Symbian was considered as a
small loss, because Nokia themselves left down Symbian, and they
officially stopped supporting Symbian S60 phones. The article also
mentionned that Thunderbird was also affected, and that is was a shame
for such a populat product to not publish a serious work around within
days. A WA should have been proposed in days; it's now one year, and TB
still does not compensate the loss; any mobile phone (included Linux
based Android) now use either push, or similar tech; thunderbird ...
does not.

That's why, for some key features that Thunderbird does not implement
(used to in previous versions, but does not any more), I am seriously
considering to ... install a phone emulator ... to bring back these
features in my desktop. Gonna use a foreign arch emulator to work around
regressions of Thunderbird !!!

The best MUA ever was Thunderbird 1.5 .
