Now I can easily parse what you wrote (the call stacks were heavy)
after I've added fprintf() to builtin.c / typeset_single. Indeed, it
is called before first run of special-autoloaded functions. On second
run there's no "local FPATH" being run, and further-autoloaded
functions are not found. I simplified my test case and just run uizcm
twice. During second run new autoload functions aren't resolved. Turns
out a normal fpath-extending loading support is needed for Zplugin,
unless a creative solution is found
