TODO:

- [x] Check if removal of `requestAnimationFrame` is possible to avoid
flash of content. Likely needs a `MutationObserver`.
- [x] Hide tippy when button is removed from DOM.
- [x] ~~Implement right-aligned items
(https://github.com/go-gitea/gitea/pull/28976)~~. Not going to do it.
- [x] Clean up CSS so base element has no background and add background
via tailwind instead.
- [x] Use it for org and user page.

 # Guidelines
 
-* These components are loaded in `<head>` (before DOM body),
-  so they should have their own dependencies and should be very light,
-  then they won't affect the page loading time too much.
-* If the component is not a public one, it's suggested to have its own `Gitea` or `gitea-` prefix to avoid conflicts.
+* These components are loaded in `<head>` (before DOM body) in a separate entry point, they need to be lightweight to not affect the page loading time too much.
+* Do not import `svg.js` into a web component because that file is currently not tree-shakeable, import svg files individually insteat.
+* All our components must be added to `webpack.config.js` so they work correctly in Vue.
