Recent updates of our dependencies seam to have introduced that a control sequence ESC + [>0;276;0c is sent by the frontend (possibly xterm) to the backend directly after the terminals are available. This leads to the string "0;276;0c" being injected in all started terminals. It seams to not happen in all situations, e.g., only if tmux is used in the instance and terminal and not on all operating systems and browsers on the client side.
