We already do this in the update pass. That's what `shouldMeasureSuspenseNode` does. We also don't update measurements when we're inside an offscreen tree. However, we didn't check if the boundary itself was in a suspended state when in the `measureUnchangedSuspenseNodesRecursively` path. This caused boundaries to disappear when their fallback didn't have a rect (including their timeline entries).
