Works a treat.

I see what you did and why, and I remember doing that when I originally did this in the chemprentice PR.

But I am extremely puzzled as to why it worked properly in my testing for the PR without that mapping in place

[Temoffy]

but that's a question for another time I suppose, even if it somehow autolinked due to the shared state reference, it is still best practice for clarity to specifically map it to a layer.

You seem to have had it here before, and this new branch didn't show the screen under test.

Looks good to me.
