recursive parameter of suspend_udpating and resume_updating not working

[leleogere]

Description of bug / unexpected behavior

There is a recursive boolean parameter in the methods .suspend_updating() and .resume_updating() of mobjects. However, if I understand correctly what it is supposed to do, I think it is broken.

If I create a mobject with an updater, and I add to it a submobjects with other updaters, when I call main_object.suspend_updating(recursive=False) all updaters get stopped.

Expected behavior

I expect main_object.suspend_updating(recursive=False) to only stop the updating of the main object, and not the ones of its submobjects.

How to reproduce the issue

Code for reproducing the problem

class RecursiveTest(Scene):
    def construct(self):
        s = Square(3).add_updater(lambda a, dt: a.rotate(dt))
        sul = Square(1).add_updater(lambda c, dt: c.move_to(s.get_vertices()[0]).rotate(-2*dt))
        sur = Square(1).add_updater(lambda c, dt: c.move_to(s.get_vertices()[1]).rotate(-2*dt))
        sdl = Square(1).add_updater(lambda c, dt: c.move_to(s.get_vertices()[2]).rotate(-2*dt))
        sdr = Square(1).add_updater(lambda c, dt: c.move_to(s.get_vertices()[3]).rotate(-2*dt))
        corners = VGroup(sul, sur, sdl, sdr)
        s.add(corners)
        self.add(s)
        self.wait(3)
        s.suspend_updating(recursive=False)  # this should only stop the main square, not the small ones
        self.wait(5)

Additional comments

I'm working on a PR linked to updaters (#1873), so I can fix this issue too if it is indeed an bug (I asked in the discord if people agree that this is an unexpected behavior but I didn't get any answers).
