VFX Editor Node List Causes Performance Issues

Version: 1.2.8.0

Frequency: Consistently

Severity: Low

Bug description:
When opening an existing project in the Visual Effects Editor, the Node List is open by default with all drop-downs expanded.

When these drop-downs are expanded, the sim stutters bad when trying to pan the view around with the developer camera. If these drop-downs are collapsed, the performance smooths out and the developer camera can be panned smoothly.
