// Implements "copy prefetch cookies": transfers cookies set during the

// prefetch from the isolated partition to the navigation environment's

// partition.

//

// M1/M2 refer to this feature's implementation milestones, not spec

// concepts:

// - Milestone 1 (current): same-origin prefetch only. The prefetch channel

//   already used the document's real partition, so isolated partition ==

//   destination partition and this function is a no-op.

// - Milestone 2 (future): cross-origin prefetch. Will iterate cookies set in

//   the isolated partition and re-add them under the destination partition

//   via nsICookieManager.

//

// Spec:

// https://wicg.github.io/nav-speculation/prefetch.html#copy-prefetch-cookies
