Is Russia Supporting Insurgency in Afghanistan?

Ok, admittedly I am slow and many of you have already thought of this, but for some reason it hit me that Russia may be supporting the Taliban in its fight against the US forces. Why would they do that, you ask. Well, during the Soviet invasion of Afghanistan the US, under the leadership of President Reagan, supported the Mujahedeen in its fight against the Soviets. Vladimir Putin, the not so behind the scenes leader of Russia was KGB and holds no love for a strong US or a successful integration of a stable Afghanistan into an American orbit. If Americans withdraw from Afghanistan and chaos resumes, then the Russians could step in as a stabilizing force, without much criticism from the US. Besides, Russians hold long grudges and this could be a win-win situation for the Russians.
