This relates to #14675

The events manager stops execution if one event returns false. This is true only if one listener is attached to the particular event.

The events manager needs to be updated to allow:

• Option to stop execution for a particular event to all listeners attached to the particular event
• Option to stop execution for all events after one listener returns false

We can use stop() to achieve this but a more configurable alternative would be nice.

Added performance enhancements as well as other changes outlined in the changelog/PR
