178139 - Undo does not scroll repositioned caret into view

Status: RESOLVED DUPLICATE of bug 168459

(Core :: DOM: Editor, defect, P3)

Description

[Jesse Ruderman]

Undoing a text-editing action in Composer does not scroll the caret into view,
so I can't see what I just undid.  Furthermore, the only feedback that Composer
accepted my Undo command was that the caret disappeared from its previous
position.  This lack of feedback caused me to hit Undo several times before
realizing I had just undone several things and didn't know what they were.

Windows Explorer has a similar bug.  Windows Explorer's "undo" is global, but
undoing an action from another folder does not open the other folder to show you
what you just undid.

I think this has been fixed twice in the past: bug 48297, bug 98745.

Not strict dataloss, but you have to be comfortable with Redo to recover after
encountering this bug.

See also bug 188184, "Undo Delete Message" should select message and scroll it
into view (mailnews).

By the definitions on <http://bugzilla.mozilla.org/bug_status.html#severity> and
<http://bugzilla.mozilla.org/enter_bug.cgi?format=guided>, crashing and dataloss
bugs are of critical or possibly higher severity.  Only changing open bugs to
minimize unnecessary spam.  Keywords to trigger this would be crash, topcrash,
topcrash+, zt4newcrash, dataloss.
