### Describe what you were doing when the bug occurred:
1. I did profiling on a list, that gets updated on each pagination api call.
2. Once the profiling was done, I moved around in the Profiler to view the Flamegraph
3. Moving to second capture, the Profiler crashed.


**DevTools version**: 4.6.0-6cceaeb67

      while (owner !== null) {
        owners.unshift(fiberToSerializedElement(owner));

   Fast path props lookup for React Native style editor.
   Could use inspectElementRaw() but that would require shallow rendering hooks components,
   and could also mess with memoization.
  function getInstanceAndStyle(id: number): InstanceAndStyle {
    let instance = null;
    let style = null;
    const fiber = findCurrentFiberUsingSlowPathById(id);
    if (fiber !== null) {
      instance = fiber.stateNode;
      if (fiber.memoizedProps !== null) {
        style = fiber.memoizedProps.style;
      }
    }
    return {instance, style};
  }
  function inspectElementRaw(id: number): InspectedElement | null {
    const fiber = findCurrentFiberUsingSlowPathById(id);
