Web Components: The "Missing Link" for Native Form Integration

I recently realized that my Web Components in AgnosticUI were missing native form integration. Without Form-Associated Custom Elements (FACE) , components often break standard browser behaviors like validation, resetting, and submission. I just published a deep dive on Frontend Masters detailing how to use the ElementInternals interface to fix this. It’s the difference between a component that "looks" like a form field and one that actually is one in the eyes of the browser. In this article, I cover: ✅ Why standard Web Components fail in forms. ✅ Implementing the ElementInternals interface. ✅ Handling validation, submission, and resets. ✅ Real-world implementation details from AgnosticUI. Special thanks to Marc van Neerven for highlighting this gap! Check out the full guide here: https://frontendmasters.com/blog/form-associated-custom-elements-in-practice/
