Request for developer feedback: customizable select

Styling form controls like the <select> element has been reported as a top developer pain point for years, and we've been working on a solution. While this work is complex and has taken a long time to get right, we're getting very close to landing this feature. A customizable version of the select element is officially in Stage 2 in the WHATWG, with strong cross-browser interest and a prototype for you to test out from Chrome Canary 130.
