[Cloudformation] - [BUG] - change-set is not correctly reflected

### Name of the resource

Other

### Resource Name
AWS::CloudFormation::Stack

### Issue Description

When we are updating the nested stack at the parent level, if I remove a resource or add a resource, it will trigger modifications for other child stacks within the changeset. For example:
AWSTemplateFormatVersion: '2010-09-09'
Description: An example template for a Step Functions state machine.
Resources:
StateMachineName:
Type: AWS::CloudFormation::Stack
Properties:
TemplateURL: https://thisisas3.s3.amazonaws.com/state

thisiss3one:
Type: AWS::CloudFormation::Stack
Properties:
TemplateURL: https://thisisas3.s3.amazonaws.com/s3one.yml

iamdummy:
Type: AWS::CloudFormation::Stack
Properties:
TemplateURL: https://thisisas3.s3.amazonaws.com/iamdummy.yml

anotherone:
Type: AWS::IAM::Role
Properties:
AssumeRolePolicyDocument:
Version: '2012-10-17'
Statement:
- Effect: Allow
Principal:
Service: codeguru-profiler.amazonaws.com
Action: 'sts:AssumeRole'
ManagedPolicyArns:
- arn:aws:iam::aws:policy/AmazonS3FullAccess
RoleName: anotherolequestionmark

In here, I will be removing the anotherone resource, but that will cause a modification to the other resources.

### Expected Behavior

As we only removed the resource 'anotherone', I will expect that only the removed resource shows in the changeset.

### Observed Behavior

When I removed one resource from the parent stack, it showed all the resources as modified even though they were not changed.

### Test Cases

AWSTemplateFormatVersion: '2010-09-09'
Description: An example template for a Step Functions state machine.
Resources:
StateMachineName:
Type: AWS::CloudFormation::Stack
Properties:

TemplateURL: https://thisisas3.s3.amazonaws.com/s3one.yml

iamdummy:
Type: AWS::CloudFormation::Stack
Properties:
TemplateURL: https://thisisas3.s3.amazonaws.com/iamdummy.yml

anotherone:
Type: AWS::IAM::Role
Properties:
AssumeRolePolicyDocument:
Version: '2012-10-17'
Statement:
- Effect: Allow

### Other Details

_No response_

Reproduce the nested AWS::CloudFormation::Stack update using the supplied parent templates and inspect the resulting change set. Compare a removal of anotherone with the reported modifications to the unchanged child stacks; done means the change set reports only the resource that was removed.
