If the SDK has already been loaded and initialized this callback will still be called. NOTE: As this callback is called during the processing of the sdk.queue array you CANNOT add any additional items to the queue as they will be ignored and dropped. (Added as part of snippet version 5 -- the sv:"#" value within the snippet script, the current version is 7)

+| sri | boolean *[optional]* | Custom optional value to specify whether to fetch the snippet from an integrity file and perform an integrity check. When this option is used, the integrity file is loaded first, affecting the load order and script execution. Hence the ld option will be ignored. Additionally, if the page navigates away before the integrity file is loaded, some events may be lost.
