** Blender 2.90 was amazing with modifier stack huge improvement! but,**
PROBLEM
I notice the viewport and render icon display layout were changed back to like in 2.82.
- MODIFIER : Viewport Display icon now on the left, Render icon on the right
- PARTICLES : Render icon now on the left, Viewport Display icon on the right
SOLUTION
- We can follow what happened in outliner which is : Viewport Display icon on the left, Render icon on the right
- So the result for Modifier and Particles were also the same, Viewport Display icon on the left, Render icon on the right
