I am aware of issues. Note that this is not a "website" in the regular sense of the word. This is actually a TUI app written in rust and compiled to wasm (and other platforms too: https://github.com/ronilan/incredible/releases) as parrt of alpha testing of the Incredible TUI framework.
Creating the screen, reading a markdown file, laying out the text, colouring it, enabling the scroll, managing it, changing the mouse pointer over the scroll bar, responding to the drag on said scroll bar, underlining the links, colouring them when they are hovered, removing colour when they are not, inverting them when they are clicked, loading the next markdown page, changing the browser URL hash, the keyboard shortcuts, Ctrl+e to select all, Ctrl+c to copy, etc. - it's all coming from Incredible TUI framework, not the browser.
Feedback on all aspects much appriciated.
