Small optimisation in firing of PostLoadEventListener(s)

Description

The handling of the PostLoadEventListener(s) could see an improvement, especially for the use cases which are heavily using 2LC as such events represent a significant portion of the load complexity.

While investigating options, I could see how the improvements could also be applied to the cases which aren't using 2LC - although the relative improvement will obviously be quite lower
