Chat Box Continuity

I experience the following behaviors consistently:

1) When in the lobby as soon as players are split up into teams something grabs focus away from the text input box even if I'm currently typing in it. This results in opening random menus when I press certain keys as I try to finish typing whatever it was I was saying. It's quite bothersome since the lobby time is already pretty short and I need to take my mouse and click in the text input box to continue typing my message.

2) When inputting text during the opening sequence if you continue to type until the game transitions you to the third person view behind your character in the spawn all of your text will be gone. It used to be that after doing this when you opened your skill purchase menu a console would appear at the bottom of the screen with a ">Say" or ">TeamSay" as appropriate but I think the recent patch fixed the console popping up.

3) When inputting text after dying if you are still inputting text when the game transitions you back to the spawn all of your text will be gone and it appears the game will have decided to open up a console at the bottom of the screen with a ">Say" or ">TeamSay" depending on what channel you were typing in.

Why isn't using the chat box a consistent experience? What's with all these interruptions?
