[Bug]: Adding Tags to S3 Buckets Causes Perpetual Drift

[tomburge]

Terraform Core Version

Terraform v1.6.2 on windows_amd64

AWS Provider Version

registry.terraform.io/hashicorp/aws v5.23.1

Affected Resource(s)

S3 buckets

Expected Behavior

Tags attached to a S3 bucket are created as defined in the variables or an error should be returned that the tags aren't formatted correctly.

Actual Behavior

2 scenarios

1. I added tags to the resource with one tag being an empty string and it deleted all tags on the resource. This scenario causes perpetual drift and an immediate plan after deploying, shows changes need to be applied.

2. I added tags to the resource with all tags not being empty strings and the tags applied properly.

This behavior does not occur on another resource I am deploying with the same Terraform which is a VPC.
