How to set a transparent background for Vim with "true color" enabled?

I've enabled true colors for Vim with success using:

set t_8f=\[[38;2;%lu;%lu;%lum
set t_8b=\[[48;2;%lu;%lu;%lum
set termguicolors

(check :h xterm-true-color for more information)

I have then enabled a true color colorscheme to try the new setting, like:

set background=dark
colors deep-space

Previously when using 256 colors I was able to get a transparent background by:

hi! Normal ctermbg=NONE guibg=NONE
hi! NonText ctermbg=NONE guibg=NONE

Now, this is not working anymore and I don't know any alternative. Is it possible to get transparent background with Vim under termguicolors?

UPDATE

I've opened an issue on Vim's issue tracker: https://github.com/vim/vim/issues/981
