Switching to esnext - fields not part of "select" are returned with "undefined"

[brianzinn]

Issue description

esnext compatibility

Expected Behavior

I was expecting switching from ES2020 to ESNext to have no impact

Actual Behavior

I am noticing that relations that are not loaded and fields that are not part of select (and are not queried - i checked the query). When the transformer applies the loaded data to an entity - it adds the extra fields unnecessarily. I am only switching the target version in my tsconfig.

Steps to reproduce

"typeorm": "^0.3.20",
"sqlite3": "^5.0.2",
"ts-node": "^10.8.0",

My Environment

Dependency	Version
Operating System
Node.js version	v18.12.1
Typescript version	5.4.5
TypeORM version	0.3.20
