89821 - incorrect text navigation with arrow keys

Status: VERIFIED DUPLICATE of bug 88164

From Bugzilla Helper:

When typing in mozilla (be it a mail message, web form, etc), it may become
impossible to navigate left or right at the end of a line.
I'm not sure exactly what's causing this, but here are some examples:

1.
Open a new mail message and type a paragraph, then type in a second paragraph
with an empty line in between them.  If you navigate through the text with the
up and down arrow keys, when you reach the empty line, try hitting the left or
right arrow keys.  Nothing happens.

The correct behavior would be to take the cursor to the end of the first
paragraph if you hit the left arrow key, and to take you to the beginning of the
second paragraph if you hit the right arrow key.
2.
Open a new mail message and type in a line of text short enough to not wrap to
the next line.  Then hit the enter key to start a new empty line.  Now hit the
left arrow key.  The cursor does not move.
The expected behavior would be to move the cursor to the end of the short line
just above.
But wait!  There's more!
(The following seems to only concern text typed into a form on a web page - like
what I'm typing in now)
While your cursor is still stuck at the empty line (you can navigate up, just
not with the left/right arrows) hit the down arrow key.  The cursor does nothing
-- just as expected, for there is no line below.  But if you hit the enter key
to create a new line the cursor jumps down two lines instead of the anticipated
one line.  Weird, eh?
