Lazyloading scrollParent reloads previously loaded

I have wrapped my components with ... and the lazyloading is working nicely.

I have noticed in the Chrome Network Inspector that on each scrollParent event not only the new component is loaded but the previosly loaded components are reloaded as well. That's a huge impact on network and performance.

I can't imagine that it's how it is supposed to work so I guess that either I'm missing something or that there's an issue.

Please kindly have a look.
