"Connected" lazyload loads simultaneously

If you have 2 lazyload each one next to the other, when the first one is in viewpost, the second one is loaded automatically.
Example:
```

```

Even if I have the inside a div, when the Component1 is in the viewport, the Component2 is loaded too

Workaround:
If you have some content between each then it loads when it is the viewport

```

```
Now Conmponent1 is loaded when it's in the viewport, and Component2 is loaded when it's in the viewport

Reproduce the issue with two adjacent LazyLoad instances containing Component1 and Component2, then inspect the LazyLoad viewport-detection entry point. Verify that the second component remains unloaded until its own element enters the viewport, including the spacer-content workaround case.
