Back link on the extension detail page does not work as expected

On the start page a user selects the "Works with TYPO3" tag "8 LTS" and the "Extension tags" "#Fluid". He gets presented a list with relevant extensions. He chooses "fluid_fpdf" to get directed to the detail page. He scrolls down and gets to the "Back to Extension List". His intension is to choose a different extension from the "previous" filtered list. BUT: The chosen filters are gone!!!
