1369434 - Returning to a threaded folder collapses all messages

Status: RESOLVED DUPLICATE of bug 223970

(Thunderbird :: Folder and Message Lists, defect)

Description

[realgrouchy]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170518000419

Steps to reproduce:

I was able to reproduce this on a fresh install with no extensions in TB 52.1.1 on MacOS 10.12.5

1. Go to a folder (e.g. inbox)
2. Click the header of the 'thread' column to turn on threading (or twice if already threaded) until all threaded messages are *expanded*.
3. Go to another folder
4. Return to the original folder.


Actual results:

All message threads are collapsed upon returning to the original folder


Expected results:

The threads should remain expanded. Presumably if I had collapsed/expanded certain threads, it should also remember the individual threading settings.

Possibly related bugs:
Bug 223970 (regarding remembering collapse state, but is about when toggling threading itself as opposed to changing folders)
Bug 482869 (regarding remembering collapse state, but is about when changing collapse state of parent folder)
Bug 521418 (relates to behaviour when closing/reopening TB)
Bug 958815 (ditto)

Yes, I can confirm this, also behaving like this in TB 45, so not a regression.

Magnus, how is this meant to work?

I agree state should ideally be remembered.

The specific steps here, using the thread column as an expand/collapse toggle, are indeed broken per the dupe bug. But using * and \ to expandAll/collapseAll was fixed to be persistent across folder changes, restarts, and even for single/multiple virtual folders (all using different view code). So that should be used instead. Bug 1192838 and friends.
