170801 - cursor location jumps when deleting quoted text

Status: RESOLVED DUPLICATE of bug 179384

(Core :: DOM: Editor, defect)

Description

[Denny Wheeler]

This happens when replying to an email; when deleting quoted text--in particular
the quoted whitespace--hitting the delete key can act as if one just hit PgUp
followed by Delete.

Denny we need a test case with step by step
instructions on how to reproduce...

I don't have a clue what you mean.  Please clarify.  Use more words--this isn't
a telegram, you're not charged by the word.  Define your terms please.
(yes, I'm feeling a bit testy today)

(and does 'commit' on this here web-page mean 'post' or 'send'?  New meaning for
the word 'commit')

To create your own test case:
Receive an email. I just reproduced the problem when replying to the two emails
I'd received which needed a reply.  And then reproduced it by hitting 'reply' to
an email from Bugzilla.

Hit 'reply'
(this is with quoting turned on)

The email will appear in the 'compose' window with a blue line to the left of
all quoted text. Or two+ blue lines if there's more than one level of quoting. 
Put your cursor on some part of the email, and select from there to the end of
the quoted part.  (or just put it at the end of the quoted *text*) There usually
will still be some quoted whitespace below that.  Hit 'delete'to remove the
selected/highlighted text--you'll still have whitespace with a blue line next to
it.  Now hit 'delete' again. Keep hitting 'delete' until there is no blue-lined
whitespace below where the cursor is.  Now hit 'delete' again. Watch the cursor
jump up one or more lines and delete the first character in a line previous to
where you'd just been.

I just tested it with the email I received asking for a test case.

If the procedure I described above doesn't give the same results, I can forward
you copies of my emails on which it has happened.  (if I knew how to forward
something via this message board)

This works for me. Could you please check with a recent build to see if you can
still reproduce this?

This bug has been fixed at some point, I think it's a dupe of 179384 (there are
a myriad of similar bugs that were fixed a while back)
