Warning: This API is now obsolete.
Renamed to callNextInstanceWithMethod().
Starting with the successor of
hand, search for a built Element instance in the handle chain that implements method
methodName and immediately execute it.
callNextInstanceMethod: typeof callNextInstanceWithMethod
hand is not associated with an Element, an error is thrown.
The exact check that is currently used when searching the handle chain is mounted Elements that have an instance method
methodName. Because only built Elements have an Element instance, this only selects Elements that are mounted and built and will not select Elements that have been replaced by a style sheet rule.
