// If more event types besides click are supported for fenced events, this
// function should operate on a global map of unfenced event_type_name ->
// fenced event_type_name. Also, these functions use raw string literals to
// represent event types. While this isn't ideal, the already-defined constants
// for event types (in the blink::event_type_names namespace) aren't exported
// by Blink's public interface. Wrapping the equivalent literals in this
// function ensures that if names need to be changed later, changes are only
// needed in one file.
