Created attachment 470244 [details] Testcase When a page contains two module scripts that both import a common dependency that throws, the second module script is executed. As I understand it, both module script evaluations should fail (with the same error thrown by the dependency), and neither module body should be executed. The test case is attached. This works as expected in Firefox and Chrome. Tested on Safari Technology Preview 190.
