Calling .focus() on a webview does not properly transfer focus in Electron 3.

Start this demo with electron version 2.0.5 to see how things are supposed to work.

npm install
npm start

Put you cursor in the text input in child1.html. Type something and press enter. The text is transfered to child2.html with the cursor focused on child2.html's text input. This is the correct and exprected behavior.

Change the electron version in package.json to 3.0.9 (or check out the branch "bug").

git checkout bug
npm install
npm start

Do the same thing and notice that the focus is not transfered to the text input in child2.html.
