描述

I'm using an ion-icon in a dropdown interface, where a user has to click an element to show the dropdown's content. Because of how ionicons is implemented, the icons inside the dropdown are not loaded instantly because the request is performed when it is visible to the user.

This, of course, is not ideal, as it shows a flicker while the icons are not downloaded. Just like what happens when you set a background-image to an element in its :hover state.

Is there any way to force the load of invisible icons?

研究方向
Investigate the current lazy loading implementation in the ionicons source, likely in the icon component (e.g., src/components/icon/icon.tsx). Identify where the IntersectionObserver or scroll based loading is triggered and how to add a configuration option to disable it. Look for similar configuration patterns in the codebase for consistency. No linked PRs or maintainer responses are visible.
