With the instructions given in Retrieve Topics based on custom field?, I was successfully able to fetch the topics given a value for the custom topic field by visiting https://domain.com/latest?custom_field=custom_field_value
However, from that page, if I click on the site logo ( or the Latest button on the top bar ), it does remove the query param (custom_field) from the URL, but the topics remain filtered on the custom_field.
On refresh, the page works as expected (as in displays all the latest topics).
How do I fix this behaviour?
