Much of the stabilization was due to the strong domestic market. Recall that Poland was the only country to avoid the 2008/2009 recession. It is tight global integration that causes recessions to spread.

Brazil also famously avoided the 2008-09 recession to a great extent, to name one example.

Tight global integration is not a bad thing. Even if we took at face value your argument that a strong domestic market protected Poland in that case, you can't cherry pick the one instance in which lower-than-expected integration was beneficial without also considering all the other times in which it was harmful.
