Delay between constructor and ngoninit

[Atikant]

I am using open layer version 4.6.17 and angular version 14. I have a click listener from the map which reads the feature being clicked and after getting the feature extracts the ID of the feature and routes to a component. The issue is the call reaches the called component immediately but there is a delay of 4-10 seconds going to the onInit function of the component. If in the constructor I add NGZone and ChangeDetectorRef and set a timeout for to detect changes the issue vanishes.
I do not understand what is the root cause of this.

I had Map running outside angular so angular wasn't able to detect changes with in the Map
