Title:
  Ubuntu.Web’s WebView.getUAString() is racy by design

Status in the base for Ubuntu mobile products:
  Confirmed
Status in Web Browser App:
  In Progress
Status in webbrowser-app package in Ubuntu:
  In Progress
Status in webbrowser-app package in Ubuntu RTM:
  Confirmed

Bug description:
  See http://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Web.WebView
  /#getUAString-method for documentation.

  This method is being called by the WebView in Component.onCompleted,
  and sets the shared context’s default user agent. If the WebView is
  instantiated with a url set, the first HTTP request is issued before
  getUAString() is called, and thus potentially with the wrong UA
  string.

  This API is racy by design, there’s really no way to fix it.

  There are currently 2 apps in the store using this API:

      com.viclog.2048
      com.viclog.flappybird

  and 3 more using it with the UbuntuWebView, which is version 0.1 of
  the API, based on QtWebKit:

      com.ubuntu.developer.andrewsomething.stackbrowser
      com.ubuntu.developer.daker.x-type
      com.ubuntu.developer.fcole90.feedspot

  Seeing those relatively small numbers, I think it’s a good opportunity
  to remove the API altogether, after ensuring that the apps are fixed
  to not use it. Documentation will need to be updated.

  
  UPDATE: as of 2014-12-11, com.viclog.2048 and com.viclog.flappybird have been updated in the store, they no longer use WebView.getUAString(). So effectively no application uses the API, and it should be safe to remove it.
