Comment:
This looks similar to #30754.
We don't pass `simple_col` anymore in master hence why I wasn't able to
reproduce. It's an attribute of the `Query`
(306b6875209cfedce2536a6679e69adee7c9bc6a).
> this doesn't get passed down to the F objects because the intermediate
CombinedExpressions don't pass on the parameter
There could a few things involved but `CombinedExpressions` effectively
doesn't pass along `simple_col`, in fact it doesn't even accepts it.
