I can't help but have a sinking feeling that this as a result of the wider trend of using only Chromium-based browsers. If they were the ones affected by this issue, I feel like it would get solved almost immediately.
I was seeing problems in Chrome a couple hours ago. In the fancy editor it was taking seconds to echo, and the cursor would jump to the start of the text, and placeholder text was not being replaced with typed text. The older editor where you have to manually enter markdown worked fine.
I assumed they had done something that botched the JavaScript of the site. Maybe some update went badly today, and it manifests differently in Firefox and Chrome?
Anyway, whatever it was either they didn’t test well in Chrome either, or they don’t use the fancy editor themselves.
It was fixed within an hour or so. I didn't even realize, surfing on reddit and it was working. I was just mindlessly surfing like I normally do and then it clicked, "oh cool, Reddit is back up".
I think GP's point was Reddit breaking Chrome would cause a big uproar and result in the issue being fixed quickly, not that Chrome has more engineers.
