@oleq what's the best solution is such cases? I assume the balloon just recognizes there's a place below, and shows there.

I don't know what is the real issue here without researching. It could be that the panel is not full-height upon opening because the content is not fully loaded yet. And that's why the algorithm assumes it will fit to the bottom of the @ marker. Then, when you scroll, the panel is fully rendered (it grew vertically) and the algorithm repositions it to the north because there's not enough space. It's a wild guess, though.
