Extern scripts being fired unreliably

Description

hi guys I still have some issues with a script tag changing HTML in my gatsby template, I found that for some reason if the function is fired multiple time with setInterval then it works there (it used to work in the live repo too but now for some reason it stopped working as well)

Steps to reproduce

https://codesandbox.io/s/ancient-bash-88u2s as you can see if the setInterval is outcommented it will be shown wrong (placeholder image of some kind?) but if you remove the // then it works again as expected

Expected result

It should show a link with hover effect and other styles etc instead of an image

Actual result

it shows only an image and not a link, in the live version when I fire the script the quality of the image will be better but doesn’t turn into a link with text (expected result)

Environment

you can see the env in the reproduction for the live site:

Hi @madalynrose, sorry being really busy lately.

First of all thanks for your answer, good to know that this issue isn’t lost in the ether 😄

I was having this issue with basically all external scripts that were supposed to create some kind of html in the DOM. I’ll look into the suggestions/guesses you were giving me, thank you!

Thank you for using Gatsby! 💜
