Today we’re excited to share our new Elements Panel. The next time you open a replay and inspect an element you’ll feel the difference.
The new Elements Panel is better in 4 ways
  1. We’ve improved the Node Picker’s underlying Stacking Context algorithm so that it is far more accurate for Cypress tests and complex pages.
  1. We re-wrote our element loading logic which brought load times down from ~10s to ~1s by replacing an N+1 cascading fetch sequence with an O(2) algorithm.
  1. We virtualized our CSS Rules list so that elements with thousands of matching rules can still be shown performantly. While in there we also improved our search UI 🙂
  1. We sped up our CSS parsing logic which in some cases was contributing 7+ seconds of pure CPU lag because of some crazy O(N^4) algorithms which are now cached. (PR)
