Is this going to lead to a fresh hell for those not on the Chromium-aide?

https://developer.chrome.com/blog/comma ... commandfor :

Chrome 135 introduces new capabilities for providing declarative behaviour with the new command and commandfor attributes, enhancing and replacing the popovertargetaction and popovertarget attributes. These new attributes can be added to buttons, letting the browser address some core issues around simplicity and accessibility, and provide built-in common functionality.

I recall past developments where Google re-wrote the rule-book on what buttons could do which broke things for other browsers. Perhaps this might not be as browserground-breaking as they claim but I don't write code for web-browsers...
