 * Browser profiling integration. Stores any event that has contexts["profile"]["profile_id"]

 * in a synchronous context. Instead, we handle sending the profile async from the promise callback and
 * rely on being able to pull the event from the cache when we need to construct the envelope. This makes the
 * integration less reliable as we might be dropping profiles when the cache is full.
