Visibility=true fires as page loads with `delayedCall` enabled

We have a page with about 14 modules on it. We want to use your sensor to track when the user scrolls the page, once per session. Because of this bug, we are seeing all of the events fire at the same time. Below is sudo code:

```
this.onModuleVisibilityChange(isVisible, 'trainer')}>

```

`onModuleVisibilityChange` updates the `trainerModuleVisible` bool to true, it is defaulted to false.

Any help would be great, as this is blocking us from analytics on these modules.
