[mu4e bug] mu4e-thread incorrect folding/unfolding

[RuijieYu]

Mu version 1.11.3. I'm running 16ce837, which is 2 weeks old master + my PR for the user mailing lists, which doesn't touch threads at all.

These following two issues might be related, so I reported them together.

---

...
Line 1 msg A1.
Line 2 msg A2 Re: A1.
Line 3 msg B1.
...

Pressing TAB on line 1 folds lines 2-3.

Expect: lines 1-2 folded.

---

...
Line 1 msg A1.
Line 2 [fold thread A].
Line 3 msg B2 Re: B1.
...

Pressing TAB on any message in thread B (e.g., line 3) unfolds the folded thread A and does not fold thread B.

Expect: thread A keeps folded, thread B now becomes folded as well.
