Initial Footer flicker with overlapping key bindings

[TomJGooding]

I noticed there seems to be a initial flicker in the Footer if there are overlapping bindings. Try running the app in the MRE below, where the space key has bindings both in the app and the widget, and watch the footer. This wasn't the case before dynamic bindings, from a very quick look into this the commit is aa6e144.

from textual.app import App, ComposeResult
from textual.widgets import Checkbox, Footer


class ExampleApp(App):
    BINDINGS = [
        ("space", "bell", "Ring the bell"),
        ("q", "quit", "Quit"),
    ]

    def compose(self) -> ComposeResult:
        yield Checkbox("Watch the Footer")
        yield Footer()


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