Description nicolo.ribaudo 2023-09-24 23:56:41 PDT 
When re-loading an already loaded module specifier, the attributes should be re-validated.


    await import("data:application/json,3", { with: { type: "json" } });
    await import("data:application/json,3");


The second import should fail, but it succeedes.

Spec: https://html.spec.whatwg.org/#fetch-a-single-module-script (it uses the `type` as part of the modules map key)
