Bug#304223: konqueror: Changing focus to/from large modified textarea causes dramatic downwards scrolling

[Adrian Irving-Beer <wisq-deb@wisq.net>]

Package: konqueror
Version: 4:3.3.2-1
Severity: normal

This bug may be related to bug #290040, but I do not know for certain,
so I'm filing it as a new report.

The best way to explain this is probably by example:

  * I pull up the Wikipedia article on the Cold War and begin editing.
  * I scroll the textarea to the middle.
  * I enter the text area.  (Note that entering and exiting does not
    do anything at this point.)
  * I remove a single letter, in this case, the "t" in "the".
  * I click on "Edit Summary".  Suddenly, the text area scrolls to the
    very bottom.

This appears to be cumulative.  If I scroll down a single line, make
an edit, and exit the box, my text area only scrolls down one line. As
I enter and exit, it scrolls down in larger and larger increments
until I reach the bottom.

If you're having trouble reproducing this, I've provided a URL,

    http://kochi.wisq.net/misc/demo/konq-scroll.html

which provides a sample web page.  Press the down arrow on the
textarea once, then delete the period after "user base".  Click on
the text box below, and the textarea should scroll down one line.
Click back and forth between the two until the document scrolls to
the bottom.
