This actually works only for the specific element order from my initial reproduction script.
The issue remains if there's more than one node after Wrapper component, i.e. https://codepen.io/alebastr/pen/OKxjgZ

Nevermind my comment, that would result into the else branch and wouldn’t save bytes to add a clause for that.

Looks great 💯

@alebastr has a good point. I'm thinking about this one.

[marvinhagemeister]

yeah this is probably not the right fix for that.
