95942 - Drag-select when rightmost text already selected doesn't work

Status: RESOLVED WORKSFORME

(Core :: DOM: Selection, defect)

Description

[Robin Green]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.3+) Gecko/20010817
BuildID:    2001081715

When the rightmost characters in a textfield or the URL bar are selected, if you
start dragging to the right of them, and drag over them, no text is selected.

Reproducible: Always
Steps to Reproduce:
1. Ensure that you have a short URL in the URL bar, so there is some unoccupied
space to the right of it.
2. Select some characters at the right of the URL.
3. Move mouse past right end of URL
4. Drag mouse leftwards
5. Release mouse button

Actual Results:  No selection. Cursor appears at end of URL.

Expected Results:  Should have selected what I dragged over. This is consistent
with, for example, konqueror in KDE 2.2.

-----------------------
The above test case is not so bad. Where it gets REALLY confusing is this "bad
user experience" case, which I thought was a hard-to-reproduce bug until I
worked out what was going on:

1. Select all of URL bar
2. Click outside of URL bar.

Selection in URL bar disappears, but it still "remembers" its selection, as you
see in the next step (is this a different bug?).

3. Click and drag from past the right end of URL, leftwards.

Actual result: Entire URL is selected WHILE you drag, but nothing is selected
after you release the mouse button!
Expected result: should select text as normal.

[sairuh (rarely reading bugmail)]

hmmm, should this go to selection?

I can confirm that this happens with 2001-09-11-21 on Linux. Also note that this
does not occur on Netscape 4.78 on Linux. The result on NS 4.x is that the text
get selected during the drag even if it is already selected before. 

Adding 4xp keyword and marking NEW.

This bug is closely related, but not a dupe, of bug #87410.

Confirming on Linux and Win98.
Just to re-emphasize, if the rightmost character is selected, then a selection
attempt from the right will cause the text to be unselected and the cursor will
be at the end.
