264526 - Keyboard selection of messages skips first entry

Status: RESOLVED EXPIRED

(SeaMonkey :: MailNews: Message Display, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922

I'm surprised that this hasn't been submitted already since I've been
experiencing it since Mozilla and now in Thunderbird but I couldn't find
anything in bugzilla.

Occasionally, keyboard selection (SHIFT+DOWN ARROW) skips the first entry.

Reproducible: Always
Steps to Reproduce:
1. Select a range of messages with the keyboard (SHIFT-UPARROW) starting lower
in the list, selecting toward the top.  Make sure to leave a few messages below
the selection.
2.Hit the DEL key to delete those messages.
3.Select a few messages, this time going downward.

Actual Results:  
The first press of SHIFT-DOWNARROW will unselect the current entry.  Successive
presses will select entries correctly.

Expected Results:  
The entry that is selected at the beginning of the select operation should stay
selected.

This is easy to reproduce with TB 0.8, and with Mozilla 1.7.2, Win2K; but I do 
not see the same symptom in Mozilla 1.8a5-1011.  I haven't installed a TB 
nightly, it might be fixed for that as well; I'll hold off confirming until I 
can verify that.

The symptom also exists in the browser -- for instance, the bookmark manager.
Maybe this is related to the patch in bug 219706?

> Successive presses will select entries correctly.

In my experience, this is not quite true; the actual items that are selected 
depends on the number of items that have been shift-selected in the first group.
Start selection on item[0].  
Select N items via (N-1) × shift-uparrow, then delete:
  item[1] is now selected.
shift-downarrow:
  item[1] is unselected
  item[2] has the focus box, but is not selected
shift-downarrow:
  item[2] is selected (and remains selected)
  item[3] has the focus box, but is not selected
... etc.
On the Nth shift-downarrow,
  item[N] is left unselected
  item{N+1] is selected (and has the focus rectangle, altho that's hard to see)

Subsequent presses continue to select as expected.

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
