Ensure enum scopes work properly with STI and inheritance

The code was changed to call `where` on a specific class in 813c8c07,
but no reasoning was given and I can't see any good reason why we would
need to do that. This will ensure that the method is called on whatever
class the scope is called on.

Fixes #23013
