### 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

   Track the intersection of currently inspected paths,
   so that we can send their data along if the element is re-rendered.
  function mergeInspectedPaths(path: Array<string | number>) {
    let current = currentlyInspectedPaths;
    path.forEach(key => {
      if (!current[key]) {

     This function helps prevent previously-inspected paths from being dehydrated in updates.
     This is important to avoid a bad user experience where expanded toggles collapse on update.
    return function isPathAllowed(path: Array<string | number>): boolean {
      switch (secondaryCategory) {
