HierarchyRequestError thrown when injecting HTML into page
Briefly

In a traditional Single Page Application (SPA) like Nuxt and Vue.js, timing issues often arise due to JavaScript rendering components into the DOM after document parsing.
Using requestAnimationFrame can help ensure elements are fully loaded before attempting to manipulate the DOM by repeatedly checking for element availability.
For slow network conditions, it's crucial to implement solutions that ensure content is injected only after the entire application is rendered, avoiding potential errors.
Delaying content injection until the application is fully ready can resolve errors linked to timing, particularly in applications reliant on client-side rendering.
