Note: This supersedes the earlier PR (#19931), which I accidentally closed while resolving the signing and build issues.

I'm sorry, but this PR doesn't contain your earlier changes to the files, only updated tests. The updated test is also nonsensical.

[MagentaManifold]

There's no point in doing this. It was to test groupByName's value, not the number of Monitor clients. If you remove groupByName you should remove this part of the test as well, and update it to test what you've added.

Thanks for pointing this out - you’re right.

It looks like the implementation commits were dropped while I was resolving the earlier signing/build issues, and only the test updates made it into this PR.

I’ll restore the original changes and update this PR accordingly.

Appreciate your patience.
