Error : Cannot setup 2 different CrossHairTool at the same time

[Celian-abd]

Hello, I was trying to setup 2 Crosshair on different viewports but when I try to activate both at the same time I got the following error :

However, when I try to activate only one of them, it works perfectly.
Knowing that I have 2 rows of 3 viewports with an unique RenderingEngineID, viewportIDs and toolgroupID for each row. Both aren't linked.

You can run a simple build here : https://github.com/Pixilib/Dat_Scan_Viewer/tree/crosshairs-sync-minimal
You only need to install cornerstone's packages and to do :
-> cd datscan
-> npm start

And then you can drag and drop the files to load the viewer.

Update : we succed to sync crosshair by displaying the two studies in the same rendering engine.
However it might still be a bug that we can set 2 cross hair on 2 rendering engine (they should not see each other, isn't it ? )

Crosshairs require a full revamp which is on my todo list
