React Daily: Suspense Fallback Stability and Selection Listener Fix
Two unrelated correctness fixes landed for React DOM: one preserves server-rendered Suspense fallback DOM across client re-suspend, and one restores missed selection events in document-root apps. The fallback fix carries the highest user-visible impact for hydration stability.

Good morning, it's Sunday, September twenty-seventh, twenty twenty-six, and this is React Daily.
Today's activity doesn't point to a single feature push. It's two separate correctness fixes, both about React mistakenly discarding something it should have kept. Of the two, the Suspense fallback fix carries the highest user-visible impact.
First, server rendering and hydration. P R thirty-seven six ninety-four addresses an issue where a Suspense boundary left as a permanent fallback on the server would briefly delete and remount that same fallback during hydration if client code re-suspended on a client-only promise, like a timer or local storage…
Second, text selection events. P R thirty-seven six ninety-six fixes missed on-select updates when the app root is the document itself, which is the setup used by Next.js App Router. The problem was a shared marker for event setup: once the root container was marked as listening, the document-level selection change…
No further action is described in the feed, but developers should expect more predictable fallback preservation on re-suspend, and should re-test selection behavior in document-root setups once this lands.
That's it for today.…
