Summary

This PR fixes a likely incorrect condition in the scheduleUpdateOnFiber function inside ReactFiberWorkLoop.js.

Previously, the code checked:

(executionContext & RenderContext) !== NoLanes

However, NoLanes is part of the lane priority system, not the execution context flags. The intent here seems to be to detect whether the current execution context includes RenderContext, which should be compared against NoContext, not NoLanes.

This fix replaces NoLanes with NoContext for semantic correctness and consistency with other checks throughout the codebase.

Fixes [#33169](#33169)


How did you test this change?

I ran the following commands to validate correctness and ensure nothing was broken:

  • yarn lint
  • yarn linc
  • yarn test
  • yarn test --prod
  • yarn flow
  • yarn prettier

All checks passed. Since this is a minor internal logic fix and doesn't change public behavior or APIs, no additional tests are necessary at this time.

## Summary

This PR fixes a likely incorrect condition in the
`scheduleUpdateOnFiber` function inside `ReactFiberWorkLoop.js`.

Previously, the code checked:

```js

````

However, `NoLanes` is part of the lane priority system, not the
execution context flags. The intent here seems to be to detect whether
the current execution context includes `RenderContext`, which should be
compared against `NoContext`, not `NoLanes`.

This fix replaces `NoLanes` with `NoContext` for semantic correctness
