WebView2Loader.dll is still missing from App.Publish (Winforms, ClickOnce).

ClickOnce is still missing WebView2Loader.dll and the x86, x64 and arm64 directories containing the various version of WebViewLoader.dll. None of which are copied to the App.Publish sub-directories when I publish using ClickOnce.

According to 228, this was supposedly fixed in 0.9.628-prerelease. That issue report is now closed, hence why I am starting a new issue report (presumably that is what is expected?).

Versions tested:
SDK 0.9.628-prerelease
SDK 0.9.579-prerelease
both the above tested with and without the amendments to the Targets file mentioned in 431 and 228, but still the files are not copied to App.Publish when publishing with ClickOnce.

Runtime: Edge Canary and Edge WebView2 Runtime. I have tried with both/either installed.
Framework: WinForms
OS: Win10
Visual Studio 2019
Building and publishing in Release mode.
Platform Target: x86 (not been able to test x64 or Any CPU, because of other DLLs in my project that require x86)

Thanks for any help, I'm out of ideas.

The issue names no source file or test entry point. Reproduce a Release WinForms ClickOnce publish with WebView2 SDK 0.9.628-prerelease and x86 targeting, then inspect the App.Publish output; done means WebView2Loader.dll and the x86, x64, and arm64 directories are copied there.
