please note: the current code for isolates in dart2js is not working correctly:
spawnFunction should spawn an isolate in a worker, and it's currently spawning
the new isolate in the DOM UI thread.

This bug is because we are not including some of the initialization of this file
in the dart2js generated code.

-    $isWorker || ((typeof $globalThis['Worker']) != 'undefined');
-function $initGlobals(context) { context.isolateStatics = {}; }
-function $setGlobals(context) { $globals = context.isolateStatics; }
-
-// Wrap a 0-arg dom-callback to bind it with the current isolate:
-function $wrap_call$0(fn) { return fn && fn.wrap$call$0(); }
-
-Function.prototype.wrap$call$0 = function() {
-  var isolateContext = $globalState.currentContext;
-  var self = this;
-  this.wrap$0 = function() {
-    var res = isolateContext.eval(self);
-    $globalState.topEventLoop.run();
-    return res;
-  };
-  this.wrap$call$0 = function() { return this.wrap$0; };
-  return this.wrap$0;
-};
-
-// Wrap a 1-arg dom-callback to bind it with the current isolate:
-function $wrap_call$1(fn) { return fn && fn.wrap$call$1(); }
-
-Function.prototype.wrap$call$1 = function() {
-  var isolateContext = $globalState.currentContext;
-  var self = this;
-  this.wrap$1 = function(arg) {
-    var res = isolateContext.eval(function() { return self(arg); });
-    $globalState.topEventLoop.run();
-    return res;
-  };
-  this.wrap$call$1 = function() { return this.wrap$1; };
-  return this.wrap$1;
-};
-
-// Wrap a 2-arg dom-callback to bind it with the current isolate:
-function $wrap_call$2(fn) { return fn && fn.wrap$call$2(); }
-
-Function.prototype.wrap$call$2 = function() {
-  var isolateContext = $globalState.currentContext;
-  var self = this;
-  this.wrap$2 = function(arg1, arg2) {
-    var res = isolateContext.eval(function() { return self(arg1, arg2); });
-    $globalState.topEventLoop.run();
-    return res;
-  };
-  this.wrap$call$2 = function() { return this.wrap$2; };
-  return this.wrap$2;
-};

-$thisScriptUrl = (function () {
-  if (!$supportsWorkers || $isWorker) return (void 0);

-  // TODO(5334778): Find a cross-platform non-brittle way of getting the
