I think this is related to #3, which I'm endlessly procrastinating to fix... I'll ping you when a fix would be available
P.S. Right now you can test the code from PR #12, see if it works

[Sebekerga]

@AndBondStyle can confirm, #12 works as expected <3

Given, it's a duplicate of #3, this can be closed, I think.
