Aaaaaahhh, NOW I get it. So sorry, I'm a bit daft sometimes 🙂
I thought you meant that sometimes the notification panel collapsed by itself after you had swiped it down, when using dark mode.
Ok, so this is another OCD thing 🙂 Definitely not a bug. I will ask our devs if they can change it but they will probably not give it the highest priority.
Thanks for not giving up haha
