User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060415 Firefox/3.0a1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060415 Thunderbird/3.0a1 ID:2006041500

If I mark a bigger block of text, at least more than one page in the editor, with the cursor (arrow down / page down) and like to 'unmark' some lines with the cursor (arrow up / page up) the cursor does not scroll upwards but remains at the last line of the editor window and the text scrolls through. This makes reading and finding the right position quite annoying. 
This behaviour cannot be seen in actual branch nightlies and was also not seen in: 
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060414 Thunderbird/3.0a1 ID:2006041308.

Reproducible: Always

Steps to Reproduce:
1. Load a text into the editor window which is longer than the window
2. Mark part of the text (arrow down / page down) so that the marked area is longer than the window
3. Scroll upwards (arrow up / page up) to unmark a smaller passage of the text
Actual Results:  
The cursor remains at the bottom of the editor window and the text scrolls through behind. 

Expected Results:  
The cursor should scroll upwards until it reaches the top of the editor window.
