Focus on the composer after exiting message template window via keyboard

When composing a message, if I open up the message template window and decide to not insert a message but instead exit the window with `ESCAPE` for example. The composer window does not get refocused and I have to use the mouse to click into the composer window so I can continue replying to someone. This breaks ergonomics pretty badly for me since I have to leave the keyboard to use the mouse, ik on the surface it seems small but there are days when I reply to 300+ messages so these things add up.
