This doesn't surprise me. Having spent years working on a very complex web app that's built to run primarily on Chrome (-2 versions), our API/DOM usage coverage was so great that we would often joke that our unit and integration tests were effectively a 90%+ coverage of all of Chrome's functionality, so any bugs or changes they made, we knew about immediately.

I think nearly every version introduced some change that broke behavior and had to be worked around, usually fairly minor and arguably reasonable. Sometimes that's not the case, something would be completely broken and we'd file bugs against Chrome to get them fixed, and our codebase is now riddled with comments about workarounds citing Chrome bugs, some years old.

There was even a recent change to contenteditable that was a breaking change and is not spec compliant, which totally breaks HTML-based rich-text editing systems built on it that don't want to just have a ton of style tags and/or empty tags everywhere in their markup. This API is probably one of the worst I've ever seen (it needs to be extensible and modifiable, you can configure it somewhat but you're left actually taking the output and massaging it yourself if you want anything resembling a good product based on it), so I'd be in full support of a rewrite of the spec and a new version of contenteditable, but as terrible as this one is, it should remain spec compliant.

At one point I held Chrome in reverence for pushing the boundary and improving the QoL of web application developers, but shifting to maintaining anything of decent complexity has made me regret the decision based on how much extra work Google makes for us. They really need to cut out the breaking changes and do better regression testing. If our app detects errors in beta/canary and we report them and they STILL make it to live, I just don't even know what to say. I'm not even sure I agree that just because 0.1% of websites rely on certain behavior that it should be "breakable." With all this talk about progressive web apps, where are the progressive web browsers?
