Canvas Recording loading goes significantly slower when "Frame" tree element is expanded

Steps to Reproduce:
1. Inspect <https://devinrousso.com/demo/DoubleHelixCircle.html>
2. Make Inspector Window very large
3. Capture a single frame recording
  => Notice frame loading is going smoothly
4. Expand "Frame 1" tree element
  => Loading goes significantly slower
