[PR2 Bug] Lobby chat scrolls to bottom when focusing on text box

[Master Raiden]

Not sure if this is a bug, but it can be a bit annoying sometimes.

Problem: Lobby chat automatically scrolls down to the bottom when you click on the message text box
Type of Problem: Client
Expected Behavior: Clicking on the message text box does not affect the view of chat messages
Actual Behavior: Clicking makes it scroll to the bottom

Steps to Reproduce the Problem: 
1. In the chat lobby, scroll up a little bit
2. Left or Right Click on the message box at the bottom
The chat will immediately scroll back down to the bottom

Additional Information:
The auto-scrolling also happens when you click on other things such as:
• The Send button
• The Join Room button
• The text in the tabs
• The area containing a level and its title
• A player's username
• The area containing the contents in the level pop-up
 . . . as shown by the red rectangles in the image below

and
• Pressing Enter to send a message
