--- BEGIN ISSUE ---
AttributeError: 'SeqFeature' object has no attribute 'strand'
## Setup
- **Biopython Version:** 1.82
- **Python Version:** 3.11.5 (main, Sep 27 2023, 11:42:37) [GCC 11.4.0]
- **Operating System:** Linux-5.15.0-91-generic-x86_64-with-glibc2.35
- **Python Implementation:** CPython

## Expected Behaviour
When processing GenBank files using Biopython, each gene feature should have a 'strand' attribute.

## Actual Behaviour
The 'strand' attributes are missing for gene features in GenBank files.

## Steps to Reproduce
1. Run the following script to parse a GenBank file and check for the presence of 'strand' attributes in gene features:
   ```python
   from Bio import SeqIO

   import sys; print(sys.version)
   import platform; print(platform.python_implementation()); print(platform.platform())
   import Bio; print(Bio.__version__)

   def check_strand_in_genes(genome_file):
       count = 0
       for record in SeqIO.parse(genome_file, "genbank"):
           for feature in record.features:
               if feature.type == "gene":
                   gene_name = feature.qualifiers.get('gene', ['Unknown'])[0]
                   if hasattr(feature, 'strand'):
                       print(f"'strand' attribute exists for {gene_name} in record {record.id}")
                       count += 1
                   else:
                       print(f"'strand' attribute does not exist for {gene_name} in record {record.id}")
                       count += 1
                   if count >= 5:
                       return

   # Replace 'genome_file.gb' with the path to your GenBank file
   # Example file: https://www.ncbi.nlm.nih.gov/nuccore/U00096.3/
   check_strand_in_genes('sequence.gb')
   ```

2. Note that the output indicates the absence of 'strand' attributes for the genes.

## Observed Output
```bash
3.11.5 (main, Sep 27 2023, 11:42:37) [GCC 11.4.0]

'strand' attribute does not exist for thrC in record U00096.3
'strand' attribute does not exist for yaaX in record U00096.3
