Disabling popup blocking in CEF3

[tashimaya]

--disable-popup-blocking (http://peter.sh/experiments/chromium-command-line-switches/)

Is this Chrome switch supported in CEF3? Is there an equivalent setting for this in CEF3?

What is the problem that you're trying to fix?

I was looking for a way to disable pop-up blocker in CEF3 and found this post. In my case, one of the hosted page explicitly checks for pop-up blocker status and shows an error message when it is not disabled.
Can I use --disable-popup-blocking in OnBeforeCommandLineProcessing method (CefApp class) to disable pop-up blocker?
commandLine.AppendSwitch(@"--disable-popup-blocking");
I tried it, but I didn't see any difference, so checking it here.
Thanks.

What exactly is this page checking for?
