We've verified the issue and @Findeton has designed a temporary patch that we'll merge next week.

We also expect the larger refactor of the query layer that we are planning in the coming weeks will generally improve the handling of cases like these by splitting query generation out into the separate database drivers.

Thanks for the detailed report!
