[Bug]: aws_s3_bucket resource incosistent with provider.aws.default_tags

[floppy-engineer]

Terraform Core Version

1.5.1

AWS Provider Version

5.8.0

Affected Resource(s)

Using together provider.aws.default_tags and resource aws_s3_bucket with additional tag give incorrect behavior.

Expected Behavior

Combine tags: from default_tags + from the resource

Actual Behavior

1. When there is no s3 bucket - terraform creates the bucket as expected with all tags
2. When the bucket is already exist and have all tags - terraform removes all tags
3. When the bucket exist and have no tags - terraform adds all expected tags.

So, continuous applying the same resource without any changes cause the cycle - 2. -> 3. -> 2. -> 3...

Agree. The behavior is just because of empty tag. Thank you very much, @maunzCache!
And I close the issue as it's a duplicate. Sorry.
