91991 - middle-click paste after end of line puts text on previous line

Status: VERIFIED DUPLICATE of bug 57913

(MailNews Core :: Composition, defect, P3)

Description

[Alex Chaffee]

STEPS TO REPRODUCE:

* Open a new Compose window
* Enter enough text to span three lines, but with no line breaks (only spaces)

e.g.

Mozilla Mail & News is a cross platform client with 
support for SMTP, POP3, IMAP, NNTP, a 
configurable three pane UI, searching and filtering,
address books, and multiple identities.

* Highlight (left-click select) a word of text (e.g. "test")

* Move your cursor just to the right of the "a" in the second line

* Middle click (paste)

EXPECTED BEHAVIOR: 
The word "test" should appear after the word "a", leaving either "a test",
"atest", or "testconfigurable" (it really should be a smart paste, which would
be "a test configurable", but that's probably too much to hope for in a
non-MacOS world).

ACTUAL BEHAVIOR:
The word "test" appears before the word "support", leaving "testsupport" at the
beginning of the second line

This is different from what happens if you use the menu or ^V paste -- that
works as expected (probably because it uses the actual cursor position, and
doesn't have to map the cursor position, which algorithm is probably busted).

Note that while entering this bug I noticed it happens in Browser text boxes
too, e.g. the Description field on enter_bug.cgi, though it is less predictable
in that case.  It also happens in the Composer : Source view, but again, it's
less predictable where it will end up.
