207199 - Can not place selection on empty line, with some text strings

Status: NEW

(Core :: DOM: Selection, defect)

Description

[Kai Engert [:KaiE:]]

This is a very bizarre bug, I hope you will be able to reproduce.
I can reproduce the bug using:
- latest official trunk from 26th of May
- a personal build from 9th of May, which was before 1.4 branched

I will attach a text string. Note that it does not end with a newline.

How to reproduce the bug:
- open the attachment
- select and copy all text, make sure you don't get any trailing linebreak. If
you want to make really sure you get the correct text, save the attachment to
your disk, open with notepad, select all, copy
- go to http://bugzilla.mozilla.org/enter_bug.cgi?product=Browser
  the page to file a new bug
- click into the "Description" field
- paste the text
the caret will now be on the end of the description field.
The last line does not wrap.
You should see an empty line before the last line.
- use the mouse and try to click at the empty line

Actual behaviour:
  You are unable to place the caret into the empty line.

For some reason, I only see the bug with that particular text.
As soon as I paste a slightly modified text, all works fine.

I also can reproduce this bug with Mozilla 1.3.1 and Netscape 7.01.

It's not likely that I will work on editor/selection bugs in the near future.
Mass assining my bugs to nobody.

The bug assignee is inactive on Bugzilla, so the assignee is being reset.
