Already saw couple posts that GG smart focus is broken and overrides stack and tiles which means GG room cannot work with others when using stack/stack and tile feature. Talked multiple times with GG support, but i doubt they are going to fix this from their side. Maybe some kind of workaround could be implemented in SAT for this issue?
The only work around is to keep the GG tables in the grid and lock them there using the "Keep table in grid" hotkey. Then the tables will never return to the stack.
Another alternative is to run two instances of SAT, and in the 2nd instance, have a separate stack/grid just for GG site only. You'd want to make sure those slots don't overlap any of the slots in the 1st instance.

Neither are great solutions but there's not much that can be done if GG refuses to allow you to turn off all table popup
