set QTabBar stylesheet as { qproperty-drawBase: 0; } not work sometime

[A Former User]

I set QTabBar style as follow:
QTabBar { qproperty-drawBase: 0; }
However, it DOESNOT work sometime after I drag the QDockWidget several times.

Is it a bug? Or did I miss something?
I also posted it at stackoverflow. But nobody answered.
