297283 - Underscores in signature disappear when deleting empty newline after signature

Status: RESOLVED EXPIRED

(Thunderbird :: Message Compose Window, defect)

Description

[Jens Kager]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050514 Firefox/1.0.4 StumbleUpon/1.9995
Build Identifier: Mozilla Thunderbird 1.0.2 (X11/20050401)

First, let me state that I am not really sure whether is a bug in Thunderbird or
rather in X, GTK2, KDE, X Font Server, my graphics driver or whatever. Still I
am filing this bug since I have only seen this happening in Thunderbird, so who
knows.

I have a signature with a line of underscores after which comes my mail address
and my website's URL, like this (without the marks for the start and end of the
signature, of course):

--------- Start Signature ---------
mfg
Jens

___________________________________
[e-mail]
http://stud3.tuwien.ac.at/~e0026337
--------- End Signature ---------

After the signature, Thunderbird creates an empty new line which is not in my
signature file. 

I noticed that under certain circumstances, when this empty new line is deleted,
all the underscores in the third-to-last line of the signature disappear. When I
then press Enter to recreate the newline after the signature, the underscores in
the second-to-last line disappear as well.


The necessary circumstances: 

1. I could only reproduce this in answers when the text of the previous mail is
quoted. The quoted text seems to need to be of a certain length, since I did not
see the effect when testing with the citation being just a single word in a
single line.

2. As implied by the earlier description, the signature must be AT LEAST two
lines long, rather three lines, for any effect to be noticed and must contain
underscores.

3. I have to delete AT LEAST two lines from the END of the quoted text I am
answering to. Then I have to insert some text of my own. Deleting from the begin
or the middle of the citation seems not to produce the bug. Before inserting
some new text, the bug doesn't appear as well.


This is not a dramatic issue; the underscores are only temporarily invisible and
don't get deleted. When selecting the lines in question they reappear, as well
as when switching away and back again to the window.

I will include screenshots of the steps to make this more understandable.

Reproducible: Always

Steps to Reproduce:
Set up a three line long signature with underscores in every line to see the
full effect (e. g. three times _a_b_, each in a new line)

1. Answer to a mail.
2. Delete two lines from the quoted text.
3. Insert own new text after that.
4. Jump to the very end of the message, behind the signature.
5. Press backspace to delete the newline Thunderbird creates after the sig. The
underscores in the third-to-last line disappear.
6. Press Enter to recreate the newline. The underscores in the second-to-last
line disappear.

Please refer to the screenshots for a visual rendering of the above.
Actual Results:  
The underscores in the second- and third-to-last line became invisible.

Expected Results:  
Nothing special ;-) Just keep the underscores visible...

I made a screenshot of every step to reproduce the bug (and thus of the bug
itself as well).

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
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
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
