The TaskAttributionTiming interface returns information about the work involved in a long task and its associate frame context. The frame context, also called the container, is the iframe, embed or object that is being implicated, on the whole, for a long task.
You usually work with TaskAttributionTiming objects when observing long tasks.
TaskAttributionTiming inherits from PerformanceEntry.
This interface extends the following PerformanceEntry properties for event timing performance entry types by qualifying them as follows:
PerformanceEntry.duration Read only Experimental
Always returns 0, as duration is not applicable for this interface.
PerformanceEntry.entryType Read only Experimental
Always returns taskattribution.
PerformanceEntry.name Read only Experimental
Always returns "unknown".
PerformanceEntry.startTime Read only Experimental
Always returns 0.
This interface also supports the following properties:
TaskAttributionTiming.containerType Read only Experimental

TaskAttributionTiming.containerSrc Read only Experimental
Returns the container's src attribute.
TaskAttributionTiming.containerId Read only Experimental
Returns the container's id attribute.
