Hello. Our company's application is experiencing very weird error.
We use custom emoji font in our app and web page. But in app browser(WKWebview) and even in Safari browser, custom emoji rendered as blank. I submitted feedback already(FB13089544), but we want to know whether others are experiencing this issue.
You can reproduce bug our font test page. [https://toss.im/tossface] Though this page only supports Korean, you can test typing in the middle of page.
