c26f470cfeis last I have by handShort description of error
In the viewport, you can't see wireframe (vertex, selected components) through a semi-transparent object
Exact steps for others to reproduce the error
75106.blend
1 - Create 2 objects one behind the other
2 - Make front object semi-transparent (via Object properties > Viewport Display > Color > Alpha
3 - Select the second object in Edit mode

Changed status from 'Needs Triage' to: 'Confirmed'
Using git bisect I narrowed down the problem commit to hash
c476c36e40which unfortunately is quite large.I thought the issue would lie in
overlay_edit_mesh.chowever this file was not changed in the commit.Added subscriber: @fclem
Unfortunately this is a side effect of the refactor which streamlined a few things. But this meant having transparent object being opaque to overlays in solid mode.
This was a design decision.
Note that this refactor brought other improvement like the possibility of having thansparent objects using in-front property.

Was this a design decision? I hope it wasn't. It makes no sense not to see vertices on Edit mode, which is by definition all about mesh edition. Using in-front property is not a solution and makes retopology harder because we can not see differences with high-res mesh properly. I hope developers listen to community and it gets reverted to 2.82 behavior.
