Confused between loadPropertyPaneResources and onPropertyPaneConfigurationStart

[hasannaqvi83]

Why are we making a call to loadLists() from "onPropertyPaneConfigurationStart" lifecycle method which fires after the property pane is opened or rendered?

There is a lifecycle method called "loadPropertyPaneResources" which provides a way to load resources needed by the property pane before the property pane is rendered and which is executed once. This way we can avoid the following check:

  if (this.lists) {
      return;
    }
