[bug] Webview does not receive keyboard events until user interaction

[alllex]

Describe the bug

My use case is to be able to use keyboard shortcuts after the app has started and the window is opened. However, this does not work until the user interacts with the window. The only interaction that enables the keyboard handling seems to be the mouse click within the window.

This problem seems to apply to the keyboard events not being propagated into the webview. Because using the regular browser keyboard events does not work, such as pressing Space key to scroll the page down.

Reproduction

1. Start a Tauri app that opens a window that is vertically scrollable (any window with long enough content)
2. Press "Space" key after the window has opened

Expected behavior

The "Space" keyboard event is propagated to the webview and the view is scrolled down.
