Chromium is changing the implementation of GuestViews (e.g. MimeHandlerView for the PDF viewer) to use MPArch inner pages instead of the current inner WebContents. In M132 this is default disabled but testable with --enable-features=GuestViewMPArch. It's currently unclear if/how this will work with off-screen rendering in CEF. See https://issues.chromium.org/issues/40202416 for background.
