Option to keep tabs toolbar without tabs when vertical tabs enabled

[N2ezr]

Recently, Nightly changed the behavior. Now, when you enable vertical tabs, the tabs toolbar disappears and all buttons from it move to the navbar.

This is definitely cool, but I would really like to be able to leave the tabs toolbar without tabs. Just as an additional toolbar. Even if it's a secret setting via about:config, still. This would be an incredibly useful feature for css theme creators, so please hear it
