I think this is fixed on master by 688d20b7cd0220af334d618608d8dfb0df250c69 and 714a3cebb3fe7e82a294d046d7fa7978e9ca8945 and that a new version needs to be released to fix it in melpa-stable.

[purcell]

I pushed a fresh tag (v0.22.0) which should resolve that

[sirgazil]

Great! I just tried it and it works. Thank you very much :)
