Research draft: The linked reports and architectural explanation below still require source verification. This is not a current-version test result.
Start with a reproducible baseline
Record the operating-system build, app version, display setup and exact action before comparing behavior across versions. A missing icon alone does not identify the API or window model responsible.
What needs architectural verification?
The single-window explanation in our research notes remains unverified. It needs a build-specific reproduction and primary technical evidence before this page can describe it as the cause of a compatibility failure.
Do not generalize one app's report
The linked Ice issue is a source to review, not evidence that the latest Ice version fails. Check the issue's affected versions, reproduction steps, maintainer response and resolution before citing a current status.
Community reports can suggest tests to perform, but cannot establish that every manager has the same cause or current compatibility status.
For safe first checks and explicitly unverified app-status notes, see the macOS 27 troubleshooting guide.
Compare workflows, not just internals
Evaluate manual reveal, icon access and automation separately on the target build. Native controls and third-party apps need their own tests; this draft does not certify the current native feature set or identify a category-wide failure.
Return to the macOS 27 column, or read the Tuck compatibility guide for the separate question of what Tuck currently supports.
