           Summary: REGRESSION: Editing text on line numbers greater than
                    'rows' attribute makes native text area scroll up
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Keywords: Regression, NativeTextArea, NeedsRadar
          Severity: normal
          Priority: P1
         Component: Forms
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: ddkilzer at kilzer.net
                CC: adele at apple.com


Steps to reproduce:

1. Open a web page with a text area (like this bug).
2. Enter line numbers on each line, then hit Enter, so that there are twice as
many lines as the 'rows' attribute for the text area is set to.  (For Bugzilla
comments, this would be 20 lines total.)
3. Move the cursor to Line 15, but make sure Line 15 is NOT the last visible
line in the text area.  (Clicking to the right of the "15" only works if you're
immediately next to the "5".  See Bug 9936.)
4. Type any character, like "a".

Expected results:

The text area does not scroll up.

Actual results:

The text area scrolls up so that the line being edited is at the bottom of the
visible area.

Regression:

This works as expected on production Safari 2.0.4 (419.3) on Mac OS X 10.4.7
(8J135/PowerPC).

Notes:

Reproduced on a locally-built WebKit r15458 with the above versions of Safari
and Mac OS X.
