Steps to reproduce:
- Go to https://payments.wikimedia.org
- Select any payment amount and any option for emails
- Click "Donate by credit/debit card"
- On the next page, click "Tax deductibility information"
- I am taken to https://donate.wikimedia.org/wiki/Tax_deductibility
- I am taken to https://foundation.wikimedia.org/wiki/Tax_Deductibility/en which is a soft redirect to https://donate.wikimedia.org/wiki/Tax_deductibility
