[tag:bug] [tag:status-completed]

Looks like [this commit](https://github.com/Glorfindel83/SE-Userscripts/commit/d67c086fa6e8a31c3b4f203a226b378275e5b0f0) broke the script on Tampermonkey on Chrome.  
The current version (0.9) doesn't work.

When I click "Detect OpenAI" it throws an error

>Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'dispatchEvent')

and points to [this line](https://github.com/Glorfindel83/SE-Userscripts/blob/1a132a19a706c3e8fa850cf7c554727da38d1a8a/openai-detector/openai-detector.user.js#L185).
