242417 - Text cursor leaves detritus during scrolling by arrow key

Status: VERIFIED DUPLICATE of bug 56913

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Greg K.]

In both Mozilla-Mac/2004042110 and Thunderbird-Mac/0.6, the blinking text cursor
leaves detritus during a scroll operation by arrow cursor key.

Note that this does not occur in HTML TEXTAREAs on web pages.

Reproducibility: Always.

Steps to reproduce:
1. Start a new message
2. Type "foo" and a linefeed; repeat until a vertical scrollbar is shown
3. Use the up arrow to move back up the page until the pane must scroll.

Expected results:
Scrolling without detritus generation.

Actual results:
Detritus left behind by the clinking text cursor.
