This might be a response by the TTY to a query that your script has
sent to it. Basically, if the script queries the TTY and exits before
reading the response, then the response goes to zle and you see this
kind of garbage on the command line.
^[[<0;24;4m is a CSI sequence. I don't remember its meaning from the
top of my head.
