The problem is that MainThreadInvoker is always using the system group, but since this call stack is touching the DOM, we can't do that here.
This does not block our rollout but it does block Quantum DOM, so I think we need to consider this high-priority.

Note QD blocked meta bug is P5... should we lower priority here?

I *think* Bill told me there are still issues with a11y and his preemptive scheduler work but I'll defer to him.

Are we still seeing these crashes? Comment 6 is moot now.

Only when preemptive scheduling is turned on, which from what billm was telling me in Austin, is not happening.
