Thanks for the image, that clears it up. Basically it's not possible with the current plugin for this to happen automatically. It looks for the active menu node based on name only.
And obviously setting the active node in the page won't work, as it's always the same page.
I believe that in the onRender method you can add a check for the Params when finding the active node. That's the only way to do it that I can see.
Let me know if you're not ok with making that change. I'm on mobile so not able to make and test that myself at the moment sorry.
