Render phase updates should not affect the `fiber.expirationTime` field. We don't have to set anything on the fiber because we're going to process the render phase update immediately. We also shouldn't reset the `expirationTime` field in between render passes because it represents the remaining work left in the update queues. During the re-render, the updates that were skipped in the original pass are not processed again. I think my original motivation for using this field for render phase updates was so I didn't have to add another module level variable.
