Hide tab bar in Vienna 3.5.7

[kikuyan]

Hello,

After updating Vienna to version 3.5.7, I see Articles tab always shown. It was not version 3.5.6 and below.
I usually don't open tabs in Vienna and I want to keep tab bar hidden when there is only Articles tab.

Is there any way to hide tab bar? I couldn't find related setting or menu item to do that.
I'm using macOS Sierra 10.12.6 if it matters.
