Well, does it make sense? If there were billions or even more of lines, your browser could also crash, your disk could be full-filled, your OS could stop responding, etc.

I can not find out what happened, as the dev tools crashed. So, for recording it, I created this issue.
Is it a way to improve or can we do something better. e.g. limit the max lines?

Most likely that the form is too big (or corrupted) then backend fails to parse it correctly to get csrf.

IIRC there are many size limits in Golang HTTP package when parsing request body
