@Dyvoker Well, it's a feature :) You can see more stickers if you like that way, while you still have no problem closing the preview (by unpressing the mouse button).

@john-preston Okay, it's unusual feature :) Usually features like this is a bugs :smiley_cat:

@Dyvoker Yes, sure, perhaps this can be named a bug. But I don't see anything bad in it, so I'll let it be that way (at least for now).
