Using the example URL for Kitty, the USE flag template shows the following USE flags: · +X Add support for X11 · test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently) · verify-sig Verify upstream signatures on distfiles · wayland Enable dev-libs/wayland backend Clicking on "+X" directs the user to https://packages.gentoo.org/useflags/+X which isn't found. Taking the + sign from the URL and going to https://packages.gentoo.org/useflags/X works. Clicking any other USE flag works. I believe the extension handling the generation of the template should strip the symbols from the USE flags before generating the URL. Reproducible: Always Steps to Reproduce: 1. Go to any wiki page with USE flag template 2. Click on any USE flag preceded by the '+' character Actual Results: The URL wrongly contains the '+' sign. The user receives "Not Found (404) We couldn't find the resource you were trying to request." message. Expected Results: The URL doesn't contain the '+' sign and the user is directed to the page for the corresponding USE flag.
