• Electron Version: 3.0.0-beta.6
• Operating System (Platform and Version): macOS
• Last known working Electron version: 3.0.0-beta.5

Expected Behavior
The onkeydown event is fired when clicking into a webview contents and typing using the keyboard.

Actual behavior
The onkeydown event is not fired.

To Reproduce

• run this fiddle: https://gist.github.com/bpasero/52358eaaf2f45f4d7e5e5e3d94a56128
• click into the input box of the GitHub landing page
• type
• observe that the onkeydown event is not emitted

This breaks VSCode's keyboard handling once focus is within a webview.
