In Chrome, the "Advanced data filters" accumulate duplicate entries

To reproduce:

1. Click "Browse All data".

2. Click "Advanced data filters".

3. Search for a patient by external ID, referer, owner, last author, or phenotype.

4. Click on the patient.

5. Click the web browser's Back button.

Expected results: The search page exactly as I left it.

Actual results: The search criteria now appear twice. When searching by phenotype this is not so bad, but when searching by external ID, referrer, owner, or last author, the duplication of criteria leads to empty search results.

This problem happens in Chrome but not Firefox.
