Interoperability matters because it ensures that the code you write for the web will work the same way for your users regardless of browser and device. The Interop project is a yearly effort where browser implementers survey developers about top pain-points and agree on areas where we will concentrate resources to drive to full interoperability.
I’m particularly pleased to see both The Popover API and CSS anchor positioning on the list, as well as View Transitions. But the whole list is great, no notes. We can watch the dashboard all year and see the score go up.
