After making this cone out of beams, I noticed that when you look away from the cone where it is not visible in the viewport, all of its beams become out of sync, which is unexpected behavior.

After looking away from cones.
REPRO: Load up the file below. Watch both cones at once and notice normal behavior, then, look at only one cone in the viewport, and then look at both again. The cone that was not in the viewport now has its beams out of sync with each other.
