description: Script is evaluated exactly once after loaded by import
esid: sec-hostimportmoduledynamically
info: |
  Success path

  The completion value of any subsequent call to HostResolveImportedModule after
  FinishDynamicImport has completed, given the arguments referencingScriptOrModule
  and specifier, must be a module which has already been evaluated, i.e. whose
  Evaluate concrete method has already been called and returned a normal completion.

  This test is meant to __not__ be flagged as module code, it should not initially
  run as module code or the result will not be the same.
includes: [fnGlobalObject.js]
flags: [async]
features: [dynamic-import]
