Textual 2.0 regression: Emoji shortcodes no longer work in labels

[godlygeek]

This program:

from textual.app import App, ComposeResult
from textual.widgets import Label


class LabelApp(App):
    def compose(self) -> ComposeResult:
        yield Label(":joy:")


if __name__ == "__main__":
    app = LabelApp()
    app.run()

looks like this with Textual 2.0:

but like this with Textual 1.x:

Is this intentional or a regression? I don't see it documented in the changelog.

Bisecting tells me that this behavior change was introduced in c9102ae

The new content system doesn't process emoji shortcodes. Experience has taught me that devs get irate when it happens accidentally. You can return Text.from_markup(":joy:") or cut and paste the emoji.

I've updated the release notes accordingly.
