Placeholder width can't be set to auto

[rodrigogiraoserrao]

Because of the (convoluted 🤪) way in which I implemented Placeholder, turns out you can't set its width to auto, otherwise the placeholder collapses.

E.g., if you run the app below, you will have an empty screen:

from textual.app import App
from textual.widgets import Placeholder

class MyApp(App):
    CSS = """
    Placeholder { width: auto; }
    """

    def compose(self):
        yield Placeholder()
