Thanks your contribution. I've done a rough review of this patch for now. On Thursday, I’ll conduct a more detailed review since I won’t be in the office this Wednesday.
I'm not sure if this is the issue you discovered. (The main patch of this pre-commit might have been lost.)

We had an internal discussion later and found that this case should be vectorizable in the form of an AnyOf reduction.
