"descendant": The script was executed in a descendant document embedded inside the current document in an <iframe>.
"other": The location of the document the script was executed in could not be determined.
"same-page": The script was executed in a version of the current document embedded within the current document in an <iframe>.
"self": The script was executed in the current document.
