`btRigidBody` with all-zero `m_linearFactor` and non-zero `m_angularFactor` will not collide with onther static objects

1

A `btRigidBody` with all zero `m_linearFactor` but non-zero `m_angularFactor` should still collide with other static objects which changes the angular velocity. But due to the code in btSequentialImpulseConstraintSolver.cpp: `solverBody->internalSetInvMass(btVector3(rb->getInvMass(), rb->getInvMass(),...

`examples/MultiBodyBaseline` is commented out in the example browser, which might explain why it was missed in bf215a3c. https://github.com/bulletphysics/bullet3/blob/e9c461b0ace140d5c73972760781d94b7b5eee53/examples/ExampleBrowser/ExampleEntries.cpp#L227 The included file is not actually used in that example. It looks...
