235559 - list pane scrolls back to selected message after clicking on junk icon of other message

Status: NEW

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Daniel B.]

User-Agent:       
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113

In the message list pane's message list, if you click on a message's 
icon to mark it as junk, then when the message disappears from the list 
(e.g., when things are configured to move junk messages to the Junk 
folder), the list scrolls to any selected message.   That is, it 
scrolls away from where you were (where you might have been about to 
mark a neighoring message as junk).

It sounds like the wrong set of events is being used to scroll any
selection into view.  (E.g., using the up and down arrow to select 
the previous or next message and having the list scroll to the 
newly-selected message makes sense.  However, the removal (or addition) 
of a message should probably _not_ reposition the list.)

 

Reproducible: Always
Steps to Reproduce:
1. Select a message in the message list.
2. Scroll away from the selected message.
3. Click on the mark-as-junk icon for another message (with things 
   configured to remove the marked message from the current mail folder).


Actual Results:  
The list scrolled to make the selected message (from step 1) visible.

Expected Results:  
The list should have remained positioned approximately where it was 
before the second message was deleted.  ("Approximately" allows for 
adjusting for the very beginning or end of the list, and for the fact 
that the junked message is gone, so the top and bottom visible items 
can't both be displayed what they displayed before the deletion.)

This sounds somewhat similar to bug 209748 -- but testing for this bug, which I 
reproduced easily, the symptom from that bug did not manifest.

Reporter (Daniel B) -- are you still seeing this symptom?  I've never been able 
to reproduce it.

Yes.  I still see it with
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040616
on Windows XP.

Hmm.  Too bad we can't see each other's screens to notice some possibly
obvious difference in our setups.

What steps did you perform to try to reproduce it?

I am seeing another problem with an unrequested scrolling but I think it is related.

When you have one message selected in the middle of the list pane, switch to
another folder and then come back, the list has scrolled up to put that selected
message at the bottom of of the list. You then have to scroll down to see the
rest  (or end) of the list below this one.

Well, I am seing this with Thunderbird/Linux. Should it be a new bug or can you
reproduce it too in MailNews/XP?

Hrm.  Looking back at this, I'm not sure why I posted comment 2 or what exactly 
I meant by comment 1.

In TB, at least, this bug is easy to reproduce: bug 264973.
