This patch doesn't change behavior. The "InProcess" version of this API (which we're migrating to in this patch) is used to annotate GetCrossDocParentFrame() callsites that have been vetted as being OK with the fact that this API returns null at the boundary of a cross-origin iframe, if fission is enabled. The call that's being migrated here is about propagating the NS_FRAME_IN_POPUP state-bit into subframes that are nested inside of a popup. This bit is used to detect cases where the display root frame is different from the document frame. We don't need to propagate the bit across process boundaries, because the child process will have its own display root frame, distinct from that of the parent process. So we're OK to use the "InProcess" version of the API here. Differential Revision: https://phabricator.services.mozilla.com/D113546 |
