Keeping up with CSS bugs via wpt.fyi
So apparently wpt.fyi provides a comprehensive look at the status of known bugs complete with automated tests so I don't have to manually check them.
In addition it's a lot more detailed and nuanced than I could have done myself.
I discovered it in this bug I submitted for Safari, in which someone mentions that the bug is fixed.
Well, it's fixed in the technology preview release, so not fixed in production. But at least now I know the official fix will be coming soon (update: fixed in Safari 16.4).
In another example, I thought the "CSS Keyword in Custom Property Fallback" bug was resolved, and when I checked wpt.fyi it showed me that it's still broken for Firefox and Safari if you try to apply the keyword to another custom property.
Thankfully for my purposes (creating a CSS framework) I'm not relying on this edge case, but in case I ever need to I will know that this bug exists.
Showing this level of detail makes my development a lot easier as I know exactly what's not working, which browser is the culprit, and when the issue is fixed without having to manually test every preview and nightly release.
Such a useful site to have.
