We are no longer implementing bugfixes for versions of Electron <= 1.7.x, so i'm going to close this issue but if it is still persisting in more recent versions of Electron we can certainly reopen it!

Just tested on 3.0.11. This is still an issue.


    webPreferences: {
      nodeIntegration: false, 
      contextIsolation: true,
      webviewTag: true,

<webview> does not work.

You know how important contextIsolation is for security, yet issues like this one make it impossible to use it in production. I think this issue should be prioritized.
