@hiroshige-g and/or @domfarolino do you think Chrome would be willing to change this? |

I'm just getting back from vacation, so I'll try and take a look this week. |

I'm willing to implement this in Chromium, so I guess we should get signals from WebKit/Gecko now. |

This CL implements whatwg/html#9407, which makes the request referrer for dynamic import() requests equal to the referring script's base URL. This already was the case for static imports, but now we do the same for dynamic imports. The implementation is more complicated than the spec change because in the spec, "fetch a single module script" takes in a referrer for use in fetching, whereas in our implementation, we don't compute the referrer until later in the process, and by this time we already have lost access to the `ReferrerScriptInfo` that we have for dynamic imports. So the way this CL works is that inside `DynamicModuleResolver::ResolveDynamically()`, we capture the referrer script's base URL (for use as the referrer in the import request) — and pass it through as a new optional parameter, simulating the spec's already-existing `referrer` parameter to "fetch a single module script" — to the following methods: Modulator::FetchTree ModuleTreeLinkerRegistry::Fetch ModuleTreeLinker::FetchRoot * use the new optional `referrer` argument to create the module script request, as "fetch a single module script" does with its `referrer` parameter in the spec [1] [1]: https://html.spec.whatwg.org/multipage/webappapis.html#fetching-scripts:fetch-a-single-module-script-4 R=hiroshige@chromium.org Bug: 1461987 Change-Id: I538a087acfb0113cdf5efa9f69947c605b2c0593 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/4678043 Commit-Queue: Dominic Farolino <dom@chromium.org> Reviewed-by: Hiroshige Hayashizaki <hiroshige@chromium.org> Cr-Commit-Position: refs/heads/main@{#1172405}

This change removes the explicit non-propagation of the referrer for dynamic
import()calls, and fixes #3744. By doing so, it aligns fetching static and dynamic imports.Note that the spec doesn't include the explicit exception for
import()because it has been explicitly wanted, but because this distinction happened accidentally when static and dynamic imports had two separate paths and I had to add it explicitly when unifying them in #8253.Firefox currently implements the new behavior, while Webkit and Chroimum implement the old behavior.
