1661525 - When receiving many (e.g. 29) new mails, the newest one is not shown at top

Status: RESOLVED DUPLICATE of bug 479969

(Thunderbird :: Folder and Message Lists, defect)

Description

[u617804]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

TB 78.1.1

• have mails in inbox sorted by date, newest mail at top
• receive many (e.g. 29) new mails
• click on the inbox folder where the many new (unread) mails are in

Actual results:

Not all mails are shown. Some (maybe 8) of the newest mails are not shown.

But you can scroll up, then the missing newest mails appear in the list.

I watched this bug now several times (maybe 10 times). I think it is alwas the case and therefore should be easy reproducable, just receive >=29 new mails in one incoming folder.

Expected results:

The newest mail shot be shown at top right away.

Happened just again, and I took screenshots. (now with TB 78.2.0)

I received 31 mails, but only the oldest 18 are shown.
The problem is, that the scroll slider on the right side, is not at the top.
(screenshot 1)

When scrolling up, the newer mails show up (screenshot 2).

Is your request that it would automatically scroll to top when new messages get added? That doesn't sound reasonable - the user may be looking at the list and checking e.g. which mails to select.

My request is, that when I start TB, TB fetches automatically new mails, and go to a folder with new messages which are sorted with the newest at top, then the newest message is shown on top and the scroll slider is also on top.
I do not want to start reading the new mails in the middle, but from top.

I do not know for sure if I never got 30 mails at once with TB68 and before, but I cannot remember having seen this with TB68 and before.

With TB78 I recognized this user-unfriendly, weird behavior at once.

Looks like to reproduce the bug, one must not have the folder with the new messages "active" (on focus) right on start.
If the folder with the new mails is already on focus on start, the scroller slider is right on top, as expected.

I can confirm, the bug is only if at TB (78.2.2) startup, the folder with the many new mails is not on focus("opened"), but another folder (e.g. "sent" folder). After clicking on the inbox folder with the many new mails, it jumps somewhere in the middle of the new mails, not as expected to the top.
