[BUG]In the latest versions rich "Title" without color

[snooppr]

rich v 13.0.1 Title is painted over, see screenshot
rich v13.9.4r Title unpainted, see screenshot

OS GNU/Linux and OS Windows

from rich.console import Console
from rich.panel import Panel
from rich.style import Style
import os

console = Console()
console.print(Panel(str(os.environ), title='[bold white]Title[/bold white]', style=Style(color="white", bgcolor="blue")))

Title should be like on the first screen (white on blue), in the second case (updated rich) white on dark (bug?)

Filling the title with a separate color does not solve the problem (it is also not completely filled).

Correct result (1 screen, completely painted over header). Workaround is to use rich v 13.0.1.
Is there a fix planned?
