Content.from_rich_text(): conceal and overline styles are recognized but not rendered

The bug

Content.from_rich_text() recognizes conceal and overline (i.e. no MissingStyle exception), but these styles are not rendered.

Note: I did ensure my terminal was able to render these styles using:

• echo -e '\x1b[53moverline\x1b[0m\x1b[21mdoubly-underlined'
• rich --print '[overline]overline[/][underline2]doubly-underlined[/]'

MRE

#!/usr/bin/env python3
from textual.app import App, ComposeResult
from textual.content import Content
from textual.widgets import Label

STYLES = ("bold", "conceal", "italic", "overline", "reverse", "strike", "underline", "underline2")

class ConcealOverline(App):
	def compose(self) -> ComposeResult:
		yield Label("conceal and overline no longer work:")
		rich_markup = " ".join(f"[{style}]{style}[/]" for style in STYLES)
		content = Content.from_rich_text(rich_markup)
		yield Label(content)

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