The applied optimisation may have been valid as long as it was
constrained to `Slider`. But it is not, as `SliderTailCircle` stores a
local copy of the object position. And as the commit message of
ce643aa68f states, this could be bypassed
by some pretty hacky delegation from `SliderTailCircle.Position` to the
slider, but it'd also be pretty hacky because it would make flows like
`PositionBindable` break down.
Long-term solution is to probably remove bindables from hitobjects.
