Details

Nothing in the code to call a Debugger's onGarbageCollection hook creates an AutoDebuggerJobQueueInterruption or an EnterDebuggeeNoExecute.

I don't see why it should be necessary to permit debuggee execution from this hook, or why it should be a problem to forbid it. Certainly omitting ADJQI and its accompanying runJobs call means that any asynchronous execution from the hook will be interleaved with content microtasks, which is asking for trouble.
