Description of bug / unexpected behavior
Consider this code:
class Debug(ThreeDScene):
def construct(self):
t0 = MathTex(r"{{ \mathsf{return} }} \ {{ z }}")
t1 = MathTex(r"{{ \mathsf{return} }} + {{z}}")
VGroup(t0,t1).arrange(DOWN)
self.play(Write(t0))
self.play(Write(t1))
self.wait(2)
Expected behavior
I would expect both lines to print the z.
Observed behavior
Yet, I only see the z on the second line. It seems like if I enclose all terms in my equation and that only empty elements are left, then only the first group is displayed. This is also seen in the bot in discord https://discord.com/channels/581738731934056449/1019649969596153968/threads/1153663738717679728
