Placeholders not being substituted after completion

[pennypatrick09]

In vim-snippets, I could create snippets by:-

snippet c "CSS Color Property" b
color: #${1:000};
endsnippet

where the 000 would be replaced when I started typing.

In nvim-data/site/autoload/emmet-vim/autoload/emmet.vim file,
there is a line :-
\ "c": "color:#${1:000};",
where I think 000 is supposed to act as a placeholder.
But the completion expands c as color: #|000; ( | being my cursor position) and the 000 remains after I type.

And I don't know if this was issued already, I would be glad if I could make it work.
