    <thetext>Unicode characters with the Emoji_Presentation property should by default (unless followed by U+FE0E to request text-style presentation) be displayed using an emoji-style font, even if the codepoint happens to be supported by the current (text) font being used.

Testcase: https://codepen.io/jfkthame/pen/jOyYPJq?editors=1100

Here, both the BLACK MEDIUM SMALL SQUARE and UMBRELLA WITH RAIN DROPS have Emoji_Presentation=YES according to https://www.unicode.org/Public/UCD/latest/ucd/emoji/emoji-data.txt, and therefore are expected to be rendered in emoji style.

Safari correctly renders them with the emoji font when explicitly followed by U+FE0F, but as the testcase shows, it fails to do this by default when no variation selector is present.

In contrast, Firefox renders this example entirely as expected.</thetext>
