LibJS: Use HostImportModuleDynamically in ShadowRealmImportValue Now that module loading is implemented this just works :^). Since ShadowRealm explicitly passed a null ScriptOrModule we attempt to get the top most ScriptOrModule in HostImportModuleDynamically. This won't work in general as the web specifies other behavior but for LibJS there must always be an active script to call HostImportModuleDynamically. 2022-01-19 10:26:38 +01:00			`await Promise.resolve(0);`

LibJS: Perform TLA async function construction in the module context Previously it was only pushing the module context for the call to capture the module execution context. This is incorrect, as the capture occurs upon function construction. This resulted in it capturing the execution context that execute_module was called from, instead of the newly created module_context. https://github.com/LadybirdBrowser/ladybird/blob/f87041bf3a8c76dce547dbd1f64d32b119f5468c/Libraries/LibJS/Runtime/ECMAScriptFunctionObject.cpp#L92 This can be demonstrated with the following setup: index.html: ```html <script> var foo = 1; </script> <script type="module"> import {test} from "./scriptA.mjs"; </script> ``` scriptA.mjs: ```js function foo() { return {a: "b"}; } export let test = await foo(); ``` Before this fix, this would throw: ``` [TypeError] 1 is not a function (evaluated from 'foo') at module code with top-level await at module code with top-level await at <unknown> at <unknown> ``` Fixes #2245. 2024-11-15 15:11:48 +00:00
