Longtask
A long task event corresponds to instances where the browser is unable to be responsive to user interaction (a situation typically caused by heavy data processing on the client side or bugs). It is generated when the a task blocks the main browser thread for a duration greater than 50 milliseconds. A longtask is a child event to an action event. It also has the context of the view that is currently active.
