  // Convert shared_ptr<UIManager> to a raw ptr
  // Why? Because:
  // 1) UIManagerBinding strongly retains UIManager. The JS VM
  //    strongly retains UIManagerBinding (through the JSI).
  //    These functions are JSI functions and are only called via
  //    the JS VM; if the JS VM is torn down, those functions can't
  //    execute and these lambdas won't execute.
  // 2) The UIManager is only deallocated when all references to it
  //    are deallocated, including the UIManagerBinding. That only
  //    happens when the JS VM is deallocated. So, the raw pointer
  //    is safe.
  //
  // Even if it's safe, why not just use shared_ptr anyway as
  //  extra insurance?
  // 1) Using shared_ptr or weak_ptr when they're not needed is
  //    a pessimisation. It's more instructions executed without
  //    any additional value in this case.
  // 2) How and when exactly these lambdas is deallocated is
  //    complex. Adding shared_ptr to them which causes the UIManager
  //    to potentially live longer is unnecessary, complicated cognitive
  //    overhead.
  // 3) There is a strong suspicion that retaining UIManager from
  //    these C++ lambdas, which are retained by an object that is held onto
  //    by the JSI, caused some crashes upon deallocation of the
  //    Scheduler and JS VM. This could happen if, for instance, C++
  //    semantics cause these lambda to not be deallocated until
  //    a CPU tick (or more) after the JS VM is deallocated.
