 *  will stall responses to ensure a consistent state, while this
 *  WebSocket provider assumes the connected backend will manage this.
 *
 *  For example, if a polling provider emits an event which indicats
 *  the event occurred in blockhash XXX, a call to fetch that block by
 *  its hash XXX, if not present will retry until it is present. This
 *  can occur when querying a pool of nodes that are mildly out of sync
