Bugfix: Render phase update causes remaining updates in same component to be dropped by acdlite · Pull Request #18537 · react/react (original) (raw)

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.
