[CAS] Potential Bug with given (|). [SOLVED]

[CH3791]

Good evening/morning to the good folk at HP,
For some maths questions, I have to restrict the domain. So I use the given symbol (|) in CAS. I would have something like:
solve(x^2-8=0,x)|(x>0)
That works perfectly.

But when I add another condition like so:
solve(x^2-8=0,x)|((x>0) AND (x<10))
The calculator creates a CAS variable called x, in the form of a matrix. And from this point on, the variable x will always have the "temporary" domain imposed onto it.
solve(x^2-8=0,x) will start to return 2*root(2) only.
solve(x+3=0,x) will give [].
and so on.

Unless this is an actual feature, can you guys fix this bug ASAP. Because I can already imagine how dangerous this would be for examinations...
