Issue in copying the URL of icon's page

[Taussy10]

On the https://icons.expo.fyi/Index website, whenever I select an icon and go to its details page — for example, this one — then copy the URL of that icon's details page, and paste it into a new tab, it doesn't open the correct page.

Instead of opening the full URL like https://icons.expo.fyi/Index/AntDesign/stepforward, it just opens https://icons.expo.fyi/Index.

Thanks
