Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

MSSiteModeEvent provides event properties that are specific to pinned site events.

This proprietary method is specific to Internet Explorer and Microsoft Edge.
