Layer Arrow Disappears
When collapsing sub-layers of a layer, the arrow to expand the sub-layers is no longer visible. Clicking the eye would restore the arrow, but this is a bug that should be fixed.
Wow. This is bizarre indeed.
Looks like Ai believes it has nothing to display, so it won’t do that at all, when all objects are hidden.
I can reproduce it.

Murad, I try to replicate it and fail. Can you share this specific file for testing?
