1823070 - inconsistent/wrong behaviour when left-arrow or right-arrow cursor keys are used on expanded threads

Status: RESOLVED WORKSFORME

(Thunderbird :: Folder and Message Lists, defect)

Description

[Calum Mackay]

113.0a1 (2023-03-17) (64-bit); MacOS Ventura 13.2.1

STR:

1. open a collapsed thread, with more than two messages
2. select a message in that thread other than the first or second message
3. press left-arrow cursor key

I'm not entirely sure what happened before SN, and can't easily check.

For me, I see one of two things happening:

• the selection jumps back to the first message in the thread; a subsequent press collapses the thread. I can live with this, although I wonder if pre-SN it just collapsed the thread on first press?

• in other threads, the left-arrow changes selection left/up just one message; it doesn't jump to message 1 in the thread, nor collapse the thread. Repeated pressing moves the selection back/left one, each time, eventually reaching the first message in the thread. This is annoying.

In the two examples I have on-screen right now, they are from different IMAP servers. Not sure if that could be relevant?

I should note that the problem is intermittent: after a restart, the thread where it was moving the selection one at a time, instead of jumping to the first, is now behaving normally, i.e. jumping to the first.

Am now seeing it occur on some threads from an IMAP server, but not on other threads from that same IMAP server. No obvious pattern to which.

Comment 3

[Calum Mackay]

Nothing in error console, in either case.

Comment 4

[Wayne Mery (:wsmwk)]

Calum, does this still reproduce with daily or beta?
I've not seen this on Mac

Comment 5

[Calum Mackay]

Yes, still seeing this today, intermittently, just tested.

To clarify, I still (today) see both of these behaviours on left-cursor key, as previously reported:

• the selection jumps back to the first message in the thread; a subsequent press collapses the thread. I can live with this, although I wonder if pre-SN it just collapsed the thread on first press?

• in other threads, the left-arrow changes selection left/up just one message; it doesn't jump to message 1 in the thread, nor collapse the thread. Repeated pressing moves the selection back/left one, each time, eventually reaching the first message in the thread. This is annoying.

from the same IMAP server (different threads).

I'm not sure what is supposed to happen? I would prefer that a single left-press closed the thread, but it never does that, only one of the above.

IMAP server is O365.

AFAICT, this behaviour is the same as it is in 102.
