Extension sometimes fails to run when custom CSS is injected
See original GitHub issueI’ve recently added some custom CSS to hide the “Explore repositories” sidebar on the dashboard. This makes the extension fail regularly with the following error (Firefox 88.0.1, RGH 21.5.19):
TypeError: document.head is null refined-github.js:1913:30
The line in question: https://github.com/sindresorhus/refined-github/blob/83f233677157d21fb6ae11958fa45aa7ee99d65a/source/features/index.tsx#L91
Since this only happens (afaik) when opening new tabs (regardless of the URL), I’m guessing the extension tries to inject the CSS before the <head> exists and thus execution stops. This was probably introduced by #4352.
Edit: can confirm the bug goes away when removing the custom CSS.

Delays never work. We need to check the dom first, that’s it. No timers will fix it. I wonder if we should just use contentScript.register to inject it. It’d be perfect on Firefox but I don’t know about Chrome (polyfilled). Its worth a try
I also had issues load too fast. I think we should up the delay to 15-20ms
