Comment:
Thanks for the detailed report!
> It seems that adding SQLiteNumericMixin to Case and ExpressionWrapper
actually fixes this, with the below patch all my testcases pass:
Yes, that should fix the issue (see related #31723 and #32585).
> I wonder if this mixing should be added to all expressions, so maybe to
Expression or BaseExpression?
This can be more complicated because "partial" expressions as `When()`
(`WHEN ... THEN ...`) cannot be wrapped.
