Created attachment 371651 [details] index.html & index.js to replicate issue on Safari + a screenshot of the issue When you try to import a name that doesn't exist from a JavaScript module, an error shows up in the console: "SyntaxError: Importing binding name 'X' is not found" however this error message cannot be read from a `window.onerror` handler. The `onerror` handler only reports: "Script error." at line 0, column 0. Example import: import { NonExisting } from "./index.js";
