This is the secondary cause of https://github.com/ppy/osu/issues/28577, because you could do the following: - Have a break autogenerate itself - Adjust either end of it to make it mark itself as manually-adjusted - Remove all objects before or after said break to end up in a state wherein there are no objects before or after a break. The direct fix is still correct because it is still technically possible to end up in a state wherein a break is before or after all objects (obvious one is manual `.osu` editing), but this behaviour is also undesirable for the autogeneration logic.
