Native Web Components Support in MDX Pages

[schae-ma]

Teams building framework-agnostic design systems using Lit, FAST, or other Web Component-based libraries currently have no straightforward way to embed and render native custom elements directly in documentation pages.
We'd love to see first-class support for native Web Components (Custom Elements v1), including the ability to load component scripts via <script type="module"> within page scope and render custom elements inline in MDX. Proper handling of properties, slots, and events would make this especially valuable for design system documentation use cases.
