Use AbortController to cancel the promise.
/code
const controller = new AbortController();
const signal = controller.signal;
// pass this signal as option in your fetch request
fetch(url, {signal}).then(...).catch(...)
// now you can reject the above promise by calling abort like this
signal.abort()
//promise will get rejected with error "AbortError"
/code
const controller = new AbortController();
const signal = controller.signal;
// pass this signal as option in your fetch request
fetch(url, {signal}).then(...).catch(...)
// now you can reject the above promise by calling abort like this
signal.abort()
//promise will get rejected with error "AbortError"

https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden Looks like this attribute can be used to preload content, or am I wrong?

Never Wrap a component with HOC inside the render method. This will cause numerous unmount and mount of same component on each render.
