Hi @paoloricciuti, and thanks for your consideration here. I agree that something needs to be added. I've provided some initial thoughts, and I'll get some other folks to look at this too.

Description
This PR adds a warning to the
Customizable select elementsarticle to warn about the fact that those features are not widely available.Motivation
The way this article is presented and described make it seems like this is the modern, generally available way to style selects ( sveltejs/svelte#15617 (comment) ). This couldn't be further from being true as this is only available in Chrome. Furthermore since the changes to the parser (again only available in Chrome) most Javascript frameworks that handle hydration will either prevent you from writing such code (like Svelte and Solid) or even worse just straight up fail hydration. It will also probably be a while before frameworks can adapt since they basically need to branch their hydration logic based on the availability of this feature.
I'm open to rephrase this if it's too scary but i think we should have some sort of warning here.
