Description

Under React 15, everything is smooth but upgrading to React 16.3.2 crashes because of rc-slider. I did not reproduce on a small case, but removing the inclusion of the slider make it work, I was willing to check if I was the only one with that problem.

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.

Check the render method of `Slider`.

Here Slider is not directly the rc-slider, it's a wrapper, replacing the actual inclusion of rc-slider make it work.

Research direction

Start with the wrapper's Slider render path and the rc-slider inclusion under React 16.3.2; the report names no file or test. Confirm whether the warning reproduces, isolate the failing component boundary, and verify the behavior after the compatibility issue is addressed.
