Discovered by Wayne. 102 has correct behaviour.

STR

  1. Set mail.operate_on_msgs_in_collapsed_threads = false (important!) (and wonder why this important ux-error-prevention pref isn't exposed in the Settings?)
  2. Have a collapsed thread with some messages above and below
  3. Select message above or below collapsed thread
  4. Press Arrow down or Arrow up respectively to navigate over the collapsed thread

Actual

  • Thread expands when navigated over, forcing users to navigate all messages of the thread before getting to the next message outside the thread.
  • This is a significant UX impediment for keyboard consumers of this pref.

Expected

  • Thread should not expand, but remain collapsed when navigating over it, to allow efficient message list navigation.
  • 102 has correct behaviour.

Other interactions with the thread's selected top message (like collapsing the thread with Arrow right or clicking on the twisty) are also blocked. Perhaps we have a wrong implementation paradigm here, which tries to realize the pref by enforcing that a collapsed thread must never be selected, i.e. whenever the top message is selected, thread is expanded?

I'm calling this a dupe of the other bug, as it's the same problem seen in two different ways.
