No actionable comments were generated in the recent review. 🎉 📝 WalkthroughWalkthroughThree widget components are modified to enhance accessibility and interaction: preview widgets are no longer explicitly disabled, markdown rendering gains keyboard focus and wheel-event capture, and textarea read-only state is no longer bound to the disabled attribute.

Remove `disabled` attribute from read-only preview textareas — disabled elements cannot receive focus, so the focus-gated wheel capture logic (#6597) always forwards wheel events to the canvas instead of allowing scroll. Add `data-capture-wheel` and `tabindex` to WidgetMarkdown display div so rendered markdown content can also capture wheel events when focused. Fixes COM-14812 Amp-Thread-ID: https://ampcode.com/threads/T-019c5a22-0e4c-7217-b022-49f9c86b8790

## Summary Restore mouse-wheel scrolling for read-only preview widgets (PreviewAny plaintext and markdown modes), broken by the focus-gated wheel capture in #6597. ## Changes - **What**: Remove `disabled` attribute from read-only textareas (keep `readonly`) so they can receive focus and capture wheel events. Add `data-capture-wheel` and `tabindex` to WidgetMarkdown display div. - **Root cause**: `disabled` elements cannot receive focus in browsers. The focus-gated `wheelCapturedByFocusedElement()` from #6597 always evaluated to false for disabled textareas, forwarding all wheel events to the canvas. ## Review Focus - Verify that removing `disabled` while keeping `readonly` does not allow unintended editing - Confirm `tabindex="0"` on the markdown display div does not cause unexpected tab-order issues - Ensure trackpad panning over unfocused widgets (#6523) still works correctly Fixes COM-14812 ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-8863-fix-restore-mouse-wheel-scrolling-in-preview-as-text-outputs-3076d73d365081719bf5e453235bb2b5) by [Unito](https://www.unito.io)
