Status: RESOLVED FIXED

We currently support process switching with DocumentChannel between content processes, and from parent->content.

This bug is for adding support for content->parent switches.

This doesn't handle the old RDM case so it depends on removing the old-RDM test in browser_tab_remoteness_change.js.
The old RDM code will be removed after the new Fission-RDM finishes riding the trains (bug 1585005).
Leaving a ni here for Micah to add a bug dependency for the cleanup bug.

Thank you everyone for your patience on this! I've created the bug responsible for removing the old-RDM tests.
