Steps to reproduce

1. Open MRP project
   • There are two sprites in a 2D scene
   • The sprite on the left is a normal sprite
   • The sprite on the right is red, and is a child of a CanvasGroup node
   • A 2D grid covering the entire screen is made using a _draw call
2. Zoom out with camera
3. Notice how the sprite under the CanvasGroup node disappears when you zoom too far out

Oddly enough, setting Y Sort Enabled = true on the canvas group fixes this issue.

EDIT: Ah, but enabling Y-sort disables the canvas group behavior altogether, therefore there's no workaround.
