Hey Kevin, I guess it’s not a problem with alignment. The flexbox behaves differently if you manually turn the display on/off and if you try to bind it. I’m attaching a short gif to visualize that.
Ha! Indeed you’re right. Thanks for noticing this @Cichy.
We’ve added it to the roadmap.
In the meantime, just had a look in one of my projects: a decent workaround would be to nest your repeated items inside a flexbox container instead of a columns element.
