Fascinating situation. 

I am trying to select elements by class name, just by typing in the Chrome Dev Tools console. I can see the elements that I want to select and they are visible on the page. I wait 3+ seconds for the page to load before I go directly to the Dev Console and type:

```
document.getElementsByClassName("example");
>> HTMLCollection []

```

Then, I right click on the element in question and hit "Inspect". I then return to the console and type:

```
document.getElementsByClassName("example");
>> HTMLCollection [div.example.row]

```

So now the elements are there! But I did nothing in Dev Tools when inspecting the elements other than hover over them. Can someone help explain this mystery? Thanks so much.

If it's any explanation, I am using [Quovo](https://api.quovo.com/docs/v3/ui/). Here is a demo: <https://youtu.be/lPcIYupa2kY>.
