Bug Scene Template Asset doesnt scale, unusable for large templates

I've made a scene template for what we consider an empty scene, and it has 2149 dependencies. When i selec the scene template asset the entire inspector stutters and freezes, its clearly struggling with this.

The entire feature is unusable because of this, nor is it helpful to have this list in the first place. Worth mentioning that the debug inspector is able to handle it much better.
