I can reproduce the issue using the code sample provided above.

Order in the screenshots below

iOS -> Android -> MacOS -> Chrome(Canvaskit) -> Chrome(HTML)

It seems on the current stable, it worked just fine on Canvaskit, but it doesn't work anymore on master. I do not see any logs in my console, either browser or terminal, on master.

Labeling for further insight from the team.

Hello, this is a low version OS issue.
There is no problem in android SDK 33 (Android 13) version, but the emoji is broken in version below android SDK 32.

Is there a way to reliably use the latest emoticons in older versions?
(as like https://developer.android.com/develop/ui/views/text-and-emoji/emoji-compat)
