Bug description

The osu!Mania editor, at least on my particular machine which runs Apple Silicon, is very laggy and causes multi-second freezes when scrubbing. The system is a MacBook Pro 16-inch 2021 model with the Apple M1 Pro chip.

A lag for a seek is same as #20221.
Later sustained frame rate drop is probably because

osu/osu.Game/Rulesets/Objects/Drawables/DrawableHitObject.cs

Lines 435 to 436 in cbed268

	if (LifetimeEnd == double.MaxValue && (state.Value != ArmedState.Idle || HitObject.HitWindows == null))
	LifetimeEnd = Math.Max(LatestTransformEndTime, HitStateUpdateTime + (Samples?.Length ?? 0));

getting skipped and hit object lifetime never ends.
