[BUG] - Using .lean() doesn't transform nested populate

[SK-FComputer]

Versions

• System: linux
• NodeJS: 16.18.1
• Typescript: 5.3.2

• Compiler / Transpiler: tsc / ts-node
• Typegoose(NPM): 11.7.1
• mongoose: 7.6.6
• mongodb: 6.0.11

What is the Problem?

Just to clarify from a start, yes i know this might be wrong usage:
Using this code to populate paths doesn't get transformed when populating paths with .lean() option.

Code Example

Structure:
User.debtor[REF].discounts[ARRAY].discount[REF]

1. Get's populated, but not transformed

UserModel.findById(id)
    .populate({
  	  path: 'debtor',
  	  populate: {
  		  path: 'discounts',
  		  populate: {
  			  path: 'discount',
  		  },
  	  },
    }).lean();

2. This works as expected (Populated + transformed):

UserModel.findById(id)
	.populate({
		path: 'debtor',
		populate: {
			path: 'discounts.discount',
		},
	}).lean();

Do you know why it happens?

no, but I'm guessing the code to populate supports the option while the code to transform/lean doesn't?

I can't upgrade to latest versions at current time, so I can't confirm but still suspect this is an issue there.

if your problem is about what .populate does at runtime, then you need to report this issue to mongoose instead of typegoose, because typegoose has no part in this (typegoose only "compiles" the class into a mongoose schema and model)

More so about what .lean does, populate works as expected. Or at least as in both code examples
But I guess the issue is still with mongoose, I'll post a bug report there.
