Character becomes stuck when sliding down steep unwalkable capsules

Characters can become stuck and unable to move as they slide against very steep capsule collision. This seems to be caused as a result of ProcessLanded begin called within UCharacterMovementComponent::PhysFalling  at 

if ( bDitch || IsValidLandingSpot(UpdatedComponent->GetComponentLocation(), Hit) || Hit.Time == 0.f )
{
   remainingTime = 0.f;
   ProcessLanded(Hit, remainingTime, Iterations);
   return;
}

Using a template project, place a large capsule collision rotated slightly to have a steep incline. Place the character above the capsule collision and begin play.

Expected: The character will slide down against the capsule until reaching a walkable floor.

Result: The character stops falling and is no longer able to change location.
