0.2.0-next.6

Release notes for 0.2.0-next.6.

Released: 2026-06-06

A focused prerelease that fixes the HTML Preview component's post-hydration layout — an Astro-to-zfb migration regression — with a backward-compatible approach that keeps existing scaffolds working on upgrade.

Bug Fixes

• HTML Preview now hydrates into the correct vertical-stack layout. On /docs/components/html-preview/ the component re-parented its preview and code sections inside the title bar after hydration, producing a broken side-by-side layout. The root cause was an island double-wrap: the bare hydration target carried the outer wrapper's displayName, so the SSG island marker resolved to the self-wrapping export and the client hydrated one level off (the same class of bug fixed for Toc/MobileToc/Sidebar in #1355). The bare inner now carries its own name and marker (HtmlPreviewWrapperInner) while HtmlPreviewWrapper stays the public <Island when="visible"> export — so host, template, and existing downstream scaffolds keep working with no call-site change and now hydrate into the correct vertical stack (title bar / preview / code) (#1925).
