Piping an alias hangs xonsh

Question

I have the following alias:

aliases['test'] = 'grep @($args) somefile'

It works perfectly fine, however when I try piping it to anything, e.g.:

$ test smth | head

it still prints out the full output of test smth ignoring the head command, and then hangs (and I can't get out of the hung state with Ctrl-C or Ctrl-Z and have to kill the session).

Any ideas on how to fix?

It's working on xonsh 0.11.0

~ $ aliases['test'] = 'grep @($args) .bash_history'
~ $ test ls | head
ls -lnrt
ls -lnrt
lsb_release -a
lspci
lspci | grep VGA
lspci
ls -l
vim 
vim
ls -l
