title: Electron(v5-v7) webview not accepting the keystrokes
body: <p>I'm writing the app with Electron and now I'm facing the issue with the webview.</p>
  
  <p>I have some webview in which there are a few text fields and one dropdown. And text fields are not working when I'm trying to tap some characters in input but the dropdown handles the <strong>up</strong> and <strong>down</strong> arrows. Also, I saw really interesting behavior: the text field's keystrokes started working when I tapped on the <strong>TAB</strong> button a few times.</p>
  
  <p>I used Electron v3 and v4 and those versions don't have that bug but they are not feasible for me.</p>
  
  <p>Someone had that issue before?</p>
