What exactly does ReactTooltip rebuild do, and when is it required?

Thanks for this awesome library. I had a question about the static rebuild method.

I have been using ReactTooltip in my application and it works in certain places. The places that it doesn’t work in requires a rebuild (like below) to make it work.

componentDidUpdate() {
    ReactTooltip.rebuild();
}

When exactly is it necessary to do a rebuild? And what is it doing? Thanks!

I was thinking, why is React Tooltip designed in a way that needs rebuilding? Why doesn’t it use mouse over event on the container to find pointed element’s potential tooltips? The way it works now, with the rebuild, feels very jQuery-esque.

@CWSites I just ran into this and it appears to be related to components with the data-for props loading later than the ReactTooltip component.

E.g. I had a dynamically loading infinite scrolling feed, and the first ‘page’ loaded the tooltip correctly for all its subcomponents. I use one tooltip to cover all those elements, which worked fine for the entries that were loaded before the tooltip was. However, if I loaded more content afterwards, the tooltip would not show for newer content. Calling rebuild() after loading new content fixed that, as it rebinds the newly loaded data-for-containing components to the tooltip.
