Dynamic import of an ~evaluating-async~ module waits for the module to finish its evaluation
info: |
ContinueDynamicImport ( _promiseCapability_, _moduleCompletion_ )
1. ...
1. Let _module_ be _moduleCompletion_.[[Value]].
1. Let _loadPromise_ be _module_.LoadRequestedModules().
1. Let _rejectedClosure_ be a new Abstract Closure with parameters (_reason_) that captures _promiseCapability_ and performs the following steps when called:
1. Perform ! Call(_promiseCapability_.[[Reject]], *undefined*, « _reason_ »).
1. Return ~unused~.
1. Let _onRejected_ be CreateBuiltinFunction(_rejectedClosure_, 1, *""*, « »).
1. Let _linkAndEvaluateClosure_ be a new Abstract Closure with no parameters that captures _module_, _promiseCapability_, and _onRejected_ and performs the following steps when called:
1. Let _link_ be Completion(_module_.Link()).
1. ...
1. Let _evaluatePromise_ be _module_.Evaluate().
1. Let _fulfilledClosure_ be a new Abstract Closure with no parameters that captures _module_ and _promiseCapability_ and performs the following steps when called:
1. Let _namespace_ be GetModuleNamespace(_module_).
1. Perform ! <emu-meta effects="user-code">Call</emu-meta>(_promiseCapability_.[[Resolve]], *undefined*, « _namespace_ »).
1. Return ~unused~.
1. Let _onFulfilled_ be CreateBuiltinFunction(_fulfilledClosure_, 0, *""*, « »).
1. Perform PerformPromiseThen(_evaluatePromise_, _onFulfilled_, _onRejected_).
1. Return ~unused~.
1. Let _linkAndEvaluate_ be CreateBuiltinFunction(_linkAndEvaluateClosure_, 0, *""*, « »).
1. Perform PerformPromiseThen(_loadPromise_, _linkAndEvaluate_, _onRejected_).
1. Return ~unused~.
_module_ . Evaluate ( )
4. If _module_.[[TopLevelCapability]] is not ~empty~, then
a. Return _module_.[[TopLevelCapability]].[[Promise]].
