Stateless function components cannot be given refs - Warning when using slider with React 16

rc-slider version: 8.4.0
react version: 16.0

When used in this context:

<Slider
          min={data.minCredit}
          max={data.maxCredit}
          step={data.step}
          value={credits}
          handle={(props) => <CreditHandle {...props} ranges={data.bonusRanges} getCurrentRange={getCurrentRange} />}
          onChange={(v) => onChange(v)}
          variation="alt"
        />

the following warning is raised

Warning: Stateless function components cannot be given refs. Attempts to access this ref will fail.

Check the render method of `ComponentEnhancer(undefined)`.
    in CreditHandle (created by ComponentEnhancer(undefined))
    in div
    in ComponentEnhancer(undefined)

Wasn't able to spot the stateless component where refs are given, maybe someone can find it?

Reproduce the warning with rc-slider 8.4.0, React 16, and the Slider usage shown in the issue. Trace the custom CreditHandle render path and ref handling, then verify that the warning no longer appears for this usage and add regression coverage if the repository has a suitable test location.
