[Docs]: running clientLoader on hydration #13329
Description
Describe what's incorrect/missing in the documentation
According to How-Tos -> Client Data:
Note that since we are not exporting a HydrateFallback component, we will SSR the route component and then run the clientLoader on hydration, so it's important that your loader and clientLoader return the same data on initial load to avoid hydration errors.
This no longer works, see #13237 which was closed stating that a HydrateFallback component export is necessary contradicting the above.
If that's how it should work now, docs require an update (happy to help with that). If it's a bug, please re-open the issue.
