The file viewer is especially strange. Scrolling is janky on iOS (presumably they are trying to control scroll position and this interferes with Safari's scroll bar). Last time I looked into the file viewer, I believe it was rendered as a web component with its own shadow DOM and a react root inside. Although off-topic for this thread, one minor annoyance is how the "improved" Issues interface no longer displays pagination controls until several megabytes of JavaScript finish loading. Meanwhile the Pull Request page, one of the oldest parts of the GitHub interface, is capable of displaying pagination controls before JavaScript loads, and it's interactive (i.e. clicking on pagination buttons will work as expected, even without JavaScript). Want to note that web-based UI doesn't have to be this way. In the case of rendering text with syntax highlighting, VS Code shows that it can be done in a performant manner. As for functionality without JavaScript, embracing standard web APIs, etc., that is exactly what frameworks like React Router (formerly Remix) are designed for.
