These tests were using chrome mochitest which forces the test page to be running in chrome and in parent process.
This doesn't reflect typical setup where the page runs unprivileged in content process.
Also, with the current bug, the pages running in system principal will be debugged with a special setup.
Actors will be run with modules loaded in a distinct loader in order to be executed
in a distinct compartment, distinct from the shared system principal compartment.
That a prerequisite for the Debugger API. It has to run in a distinct compartment than its debuggee.
Depends on D16825
