  }
}

Debug Output

None (missing)

Expected Behavior

According to Azure documentation, all tag names are limited to 512 characters. Terraform catches this before planning. However, storage_accounts are a special case where they are limited to 128 characters. When a storage account tag is planned with 129 characters, the plan should fail.

Actual Behavior

The plan ran successfully.

Steps to Reproduce

1. Build configuration with storage account having 129 character tag name
2. Run terraform plan

512 character tag names, 256 character tag values, and max 15 tags are handled. Storage accounts require this support
