 When there are more than one component linked to the same DOM node, `findInstance` navigates recursively through the react fibers looking for the instance of the right component we want. To make this process fast and avoid infinite loops there is a maximum number of iterations that the algorithm does until it decides that the instance can't be found. By default `findInstance` iterates `4` times looking for the instance and return `false` after not finding it.
