`DrawableOsuHitObject` tries to solve the initial dimming of objects
by applying transform to a list of dimmable parts. For plain drawables
this is safe, but if one of the parts is a DHO, it is not safe,
because drawable transforms can be cleared at will.
In particular, on first use of a drawable slider,
`UpdateInitialTransforms()` would fire via `LoadComplete()` on the
`DrawableSlider`, but *then*, also via `LoadComplete()`,
the `DrawableSliderTail` would update its own state and by doing so
inadvertently clear the dim transform just added by the slider.
To fix, ensure dim transforms are applied to DHOs
via `ApplyCustomUpdateState`.
The spinner max bonus was loaded through SkinnableSound instead of PausableSkinnableSound, leading to it not respecting the case where sample playback is globally disabled through ISamplePlaybackDisabler, and can be easily heard in situations like during the catchup period after seeking using the ArgonSongProgressBar with song volume at 0
