Distorted login page is shown after failed login attempt



Twitter login inside a webview on both Android & iOS is showing a distorted webpage after a failed login attempt.

Reproduce in webview (Portrait mode):

  1. go to: https://api.twitter.com/oauth/authenticate?oauth_token=AAAAAAAAAAAAAAAAAAAAAAA
  2. click the Login button without entering the credentials.
  3. login failed and the screen is replaced with a distorted Twitter login webpage (as appear in the screenshots).
