Description

On Windows, Text doesn't render surrogate pairs after some point (like flags) with the official Google Emojis fonts.

A test example is in attachements:

Emojis fonts come from Google fonts

Flags are recognized so it should be supported.

In the test example, select 'Noto Color Emoji' (by the way sometimes, when switching font, the FontDialog recenter automatically that should not happens)
Also tried without success with https://github.com/googlefonts/noto-emoji/tree/main/fonts while flags seems to be taken account (https://github.com/googlefonts/emoji-metadata/blob/main/emoji_16_0_ordering.json#L33150)
