135012 - Mouse-drag selection creates 1-pixel gap between some lines

Status: REOPENED

(Core :: DOM: Selection, defect, P5)

Description

[Mats Palmgren (inactive)]

DESCRIPTION:
Selecting by click-n-drag with the mouse creates 1-pixel gap between some of the
selected lines, not all, just a few. This is 100% repeatable at the given URL.
This never happens when selecting all text with CTRL+A.

STEPS TO REPRODUCE:
1. Goto the URL, select text in the (6th) paragraph starting "Whatever the case,
we have one heck of a contest here today ..." by left-click-n-drag the mouse.

ACTUAL RESULTS:
The text jumps down a pixel as new lines are selected leaving a gap.
It only happens in this paragraph.

EXPECTED RESULTS:
No gap / as selecting the other paragraphs.

DOES NOT WORK CORRECTLY ON:
Mozilla nightly build 2002-04-02-11 (trunk) on SuSE 7.3 Linux.

the spaces must be from a font size difference on the linux boxes.

REOPEN.

The gap between the lines appear when I select them, it is not there to begin with
nor do they appear if I select with CTRL+A. It only occurs when selecting lines
using a left-click-and-drag operation. This clearly should not happen.

Similar behaviour occurs in 2002-05-31-04 (trunk) on Windows 98 SE (Large Fonts).

I've seen this happen on Linux as well. Likely /ANOTHER/ freaking rounding bug. Ugg.

I don't know that this is a duplicate of 160342. The reporter says the gaps
appear when selecting, in my bug the text does not move it's just too wide to
start with. The reporter says the gaps do not appear when using Ctrl-A, in my
bug it's the same selecting either way.

This is not a duplicate of bug 87738.  It looks like it could be related
to bug 94739 though (but again not a dupe).

Bulk-downgrade of unassigned, >=5 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.
