I will try to bump up this question once more, since I am stuck on this

tldr: I would like to be able to use the send-break zle widget inside vared
to exit it, but when I do, the history file is cropped to one line.
Initially I had the same problem with ctrl-c, but I found out that a
trap 'return 1' INT
is able to prevent the behaviour in that case

thanks for any further help
