Float window not closing

When I open parenthesis for a function the float pops up as expected but then it never goes away. I expected the float to go away when I closed parenthesis for the function or escape out of edit mode.

float foo(int a, double b)
{
  return 1.f;
}

int main(int, char**)
{
  if(foo(1,2) 
  {
    return 1;
  }
  return 0;
}
