The issue described related to decimate modifier has been introduced recently somewhere between: ef5a362a5b - 7b0c8097a7.

Will bisect.

This seems resolved for me as well.
This was 3.0 only (so nothing to backport to LTS), guess this should be closed as resolved then?
(feel free to reopen if this is a misunderstanding)

Yes. I reported the issue after checking on the last daily build (where problem happens). But the early commit from Campbell fixed the issue.

Btw, report taken from: #90641 (Wireframe overlay doesn't work as expected (does not hide edges of coplanar faces))
