Steps to reproduce the problem:
1. Use any web app which uses websockets
2. Open Dev Tools
3. Open e.g. https://angularjs.org/
4. Search for websocket resource in network tab. In this case
   wss://s-usc1c-nss-107.firebaseio.com/.ws?v=5&ns=ng-projects-list
5. Select this enrty by clicking it
6. Force new websocket message arriving by adding new entry:
   "Wire up a Backend > JavaScript Project > + (add)"

Result:
Selection jumps to previous entry in network tab.

What is the expected behavior?
Selection must not change. Especially when analyzing websockt frames (tab) this debugging feature become unusable.

What went wrong?
Selection jumps to previous entry in network tab.
