On Windows 11 (and possibly other versions too), pressing the 'escape' key in browser via textual-serve doesn't register until the mouse is moved or until the 'escape' key is pressed again. Also, after pressing escape once, all further key strokes are "ignored" until the mouse is moved or the 'escape' key is pressed again, only then do all the keystrokes register. I'm not sure what is ultimately responsible for this: textual, the browser, or textual-serve.

Here's a tiny MRE to demonstrate this bug:

from textual.app import App
from textual import events

class TestApp(App):
    def on_key(self, event: events.Key) -> None:
        self.notify(str(event.key))

if __name__ == "__main__":
    TestApp().run()

textual serve mre.py

The following sequence can be followed: Esc, a, b, c, <mouse move> OR Esc. The a, b, c notifications will not show till the end of the sequence. Note, pressing Esc a second time causes further weirdness that moving the mouse doesn't.

At the time of this report, I'm running: textual-dev 1.7.0, textual-serve 1.1.2 and textual 4.0.0
