15547 - highlighting all screwed up

Status: VERIFIED FIXED

(Core :: DOM: Selection, defect, P3)

Description

[Warren Harris]

Do this:
- go to the mozilla page
- click and hold on some piece of text halfway down in the right-hand (white)
area
- drag down through the white area to select
- move left into the menu (black) area
- drag up through the black area
(notice that the selection goes from the bottom to the drag point -- seems
weird)

Now here's the tricky part:
- if you drag right back into the white area below the point you started and let
go, you'll have selected the text in the white area from the start point to the
end point, but...
- if you drag to the right back into the white area above the point where you
started and let go, you'll end up with all sorts of weird highlight artifacts

Double clicking on a line at this point will de-select most of the line, and
select the word that you double clicked on, but anything in a different font or
style will stay selected.

I see this on Mac (artifacts as you drag-scroll selection though not all of the
examples warren cites); reset to all platforms.  Reassign to [e-mail];
reset component to selection

I'm not sure if I understand exactly how to reproduce this bug. But, since Warren
says it's fine with him, I'm rubber-stamping as verified.
