…rder (#35021) Stacked on #35018. This mounts the children of SuspenseList backwards. Meaning the first child is mounted last in the DOM (and effect list). It's like calling reverse() on the children. This is meant to set us up for allowing AsyncIterable children where the unknown number of children streams in at the end (which is the beginning in a backwards SuspenseList). For consistency we do that with other children too. `unstable_legacy-backwards` still exists for the old mode but is meant to be deprecated. <img width="100" alt="image" src="https://github.com/user-attachments/assets/5c2a95d7-34c4-4a4e-b602-3646a834d779" /> DiffTrain build for [488d88b](488d88b)
