<p dir="auto"><strong>Note:</strong> I am well aware of the v1 branch, but since it is in beta, and I have no time right now to deal with this rather important migration, the 0.x branch needs to be supported. Projects can't always be expected to follow edge dependencies.</p>

<p dir="auto">If the Drawer component is re-rendered, the nested Paper component loses its transform style setting and the drawer is shown despite open=false</p>
