UnitofWorkManager does not manage the entity that is outside its scope #4721

• ABP Framework version: v5.3.3
• UI type: Angular
• DB provider: EF Core
• Tiered (MVC) or Identity Server Separated (Angular): yes / no
• Exception message and stack trace:
• Steps to reproduce the issue:"
• Create new solution (Abp Suite)
• Create a new entity called Book
• Add a new property called Name

when the await uow.CompleteAsync(); runs I observe that there is a change in the database

public virtual async Task UpdateNameAsync(Guid id)
{
	using var uow = unitOfWorkManager.Begin(requiresNew: true, isTransactional: true);
	var book = await _bookRepository.GetAsync(id);
	book.Name = DateTime.Now.ToString();
	await uow.SaveChangesAsync();
	await uow.CompleteAsync();
	throw new Exception("an occured exception")
}

but when the await uow.CompleteAsync(); runs in the code below, there is no change in the database. Surrounding unit of work manages book entity (instead of new uow)

public virtual async Task UpdateNameAsync(Guid id)
{
	var book = await _bookRepository.GetAsync(id);
	using var uow = unitOfWorkManager.Begin(requiresNew: true, isTransactional: true);
	book.Name = DateTime.Now.ToString();
	await uow.SaveChangesAsync();
	await uow.CompleteAsync();
	throw new Exception("an occured exception")
}

My original code similar like below. I want database changes to commit even though Exception is thrown.

public virtual async Task UpdateNameAsync(Guid id)
{
	var book = await _bookRepository.GetAsync(id);
	await UpdateNameFunctionAsync(book);
}

private async Task UpdateNameFunctionAsync(Book book)
{
	var uow = unitOfWorkManager.Begin(requiresNew: true, isTransactional: true);
	book.Name = DateTime.Now.ToString();
	await uow.SaveChangesAsync();
	await uow.CompleteAsync();
	throw new Exception("an occured exception");
}

Would you consider this a bug?
