Summary

The source attribute of ToggleEvents contains the element which triggered the ToggleEvent to be fired, if applicable. For example, if a button element with the popovertarget or commandfor attribute set up to open a popover is clicked by the user, then the ToggleEvent fired on the popover will have its source attribute set to the invoking button.
