   Where `typeString` is an internally-synthesized message type string
   used temporarily for worker message dispatching. It can be ignored
   by all client code except that which tests this API. The `row`
   property contains the row result in the form implied by the
   `rowMode` option (defaulting to `'array'`). The `rowNumber` is a
   1-based integer value incremented by 1 on each call into the
   callback.

   At the end of the result set, the same event is fired with
   (row=undefined, rowNumber=null) to indicate that
   the end of the result set has been reached. Note that the rows
   arrive via worker-posted messages, with all the implications
   of that.

   Notable shortcomings:

   - This API was not designed with ES6 modules in mind. Neither Firefox
     nor Safari support, as of March 2023, the {type:"module"} flag to the
     Worker constructor, so that particular usage is not something we're going
     to target for the time being:
