nix-mode reindents multi-line yanks

[zopa]

Say I have this nix snippet:

options = {

   enable = mkOption {
      type = types.bool;
      default = false;
      description = ''
        Whether to sync mail with offlineimap
      '';
    };
};

and starting from 'enable' I do 7yyP. I get:

    enable = mkOption {
              type = types.bool;
                        default = false;
                                  description = ''
                                              Whether to sync mail with offlineimap
                                                        '';
                                                                };

with the helpful message "Indenting region...done". So the first line aligns correctly, and subsequent lines are indented, leading whitespace and all.

Vanilla emacs with nix-mode.el loaded does not do this (using C-u 7 C-k and C-y).

I'm at a loss, I thought this was nix-mode package's fault.
