findDOMNode was called on an unmounted component

[vcarel]

We're using react-visibilty-sensor to animate pictures on our home page, and we use https://sentry.io to monitor errors on client side.

We've got multiple reports on the following issue: "Invariant Violation: findDOMNode was called on an unmounted component"
This happens in visibility-sensor.js, there:

  /**
   * Check if the element is within the visible viewport
   */
  check: function () {
    var el = ReactDOM.findDOMNode(this);
    var rect;
    var containmentRect;

(on Chrome mobile 56.0.2924)

I can't reproduce on my computer, but looks related to the tabs "Je suis propriétaire / Je suis acquéreur".

What I understand from your code is that at the end there's no real issue, because if you can't find the node you do nothing. But that warning is a bit annoying.

I presume the issue comes from a last check() call by "debounceCheck", because you don't clear the setTimeout l.21 on stopWatching

Thanks for the report @vcarel - I'll have a go at reproducing, I think you're on the right track about the cause.
