Odd chat behavior while walking forward

Steps to reproduce:

• Bind "Start Chat" to "Enter"
• Walk forward by holding left mouse button
• While moving forward, press Enter to open chat
• Type something while moving forward until text appears in the entry field
• Press Enter again while still moving forward

At this point the text entry field will be empty, but still open. No text will have been submitted to chat. On OU client, the first few characters typed will not appear, but repeated attempts to type while walking will display on screen.

What is the expected behavior? Pressing Enter again while the text entry field is open should close the field if nothing is inputted, or submit the text to chat if something is there. It should not matter if the player is moving at the same time.

This is probably related to being hardwired as the "submit" key shortcut for the text box GUI control. Will require some careful planning on how to untangle all this.
