 'preact-render-to-string': patch
 ---
 
-Fix issue where subtree re-render for Suspense boundaries caused a circular reference in the VNode's parent
+Ensure that the `_parent` is kept around across multiple suspensions and avoid circular references.
+In doing so our `useId` hook should always output unique ids during renderingToString.
