Select scroll is different with mouse vs keyboard

[TomJGooding]

This is really only a minor issue that I noticed following the fix for #5255.

There's a strange difference in the scroll behaviour when the Select is expanded with the mouse vs the keyboard.

When expanded only with the keyboard, the initial value is always the bottom of the scroll.

When first expanded with the mouse, the the initial value is also the bottom of the scroll. However after a second click, the initial value is now the top of the scroll. Subsequent expands with either the mouse or keyboard will now scroll the selected value to the top.

from textual.app import App, ComposeResult
from textual.widgets import Select


class SelectApp(App):
    def compose(self) -> ComposeResult:
        yield Select.from_values(
            range(100),
            value=15,
        )


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

Shouldn't the selected option always scroll to the top?
