Description
Description of bug / unexpected behaviour
When using the interactive ipython terminal (using self.interactive_embed() function and OpenGL renderer), the phi(polar angle) value for the orientation of the camera does not increase beyond 90 DEGREES or decrease below -90 DEGREES. Note that the theta(azimuthal angle) value does increase beyond 90 DEGREES.
But when using (in interactive mode) self.move_camera(phi=100 * DEGREES, theta=100 * DEGREES), the camera does move to an orientation that has a phi value more than 90 DEGREES.
It is only during the 'manual change of view' (or change in orientation of camera) in interactive mode, that the phi value was not increasing beyond 90 DEGREES.

Expected behaviour
The below video shows the expected behaviour which was rendered using self.move_camera(phi=120 * DEGREES, theta=30 * DEGREES). Here, the phi(polar angle) value has increased more than 90 DEGREES, which was not happening during the manual change of view in interactive mode.

How to reproduce the issue
Code for reproducing the problem
from manim import *
class ThreeDCameraRotation(ThreeDScene):
def construct(self):
axes = ThreeDAxes()
circle=Circle()
lab = axes.get_z_axis_label(Tex("$z$-label"))
self.set_camera_orientation(phi=50 * DEGREES, theta=30 * DEGREES)
self.add(circle,axes, lab)
self.interactive_embed()NOTE: you have to add --renderer=opengl flag
