Question: evala(e) still does not equal e

I'm perplexed by the fact that this bug is not fixed in Maple 2018:

seq(alias(a[i] = RootOf(_Z1^6-3*_Z1^2-2*_Z1+11, index = i)), i = 1 .. 6);
ee := a[1]*a[5]+a[2]*a[6]+a[3]*a[4];
evala(ee); # wrong
     -320/449*a[1]-(16/449*(a[2]^2))*a[1]^4*a[3]-(16/449*(a[2]^3))*a[3]*a[1]^2-
     (56/449*(a[2]^2))*a[1]^3*a[3]-(16/449*(a[2]^2))*a[1]^5*a[3]+(32/449*a[2])*
     a[3]*a[1]^5-(60/449*(a[2]^2))*a[1]^2*a[3]-(256/449*a[2])*a[1]*a[3]+(64/449*
     a[2])*a[3]*a[1]^2+(128/449*(a[2]^2))*a[3]*a[1]-(32/449*(a[2]^3))*a[3]*a[1]^3-
     (16/449*(a[2]^3))*a[3]*a[1]^4-(24/449*a[2])*a[3]*a[1]^4+(256/449*a[1])*a[2]+
     (88/449*(a[1]^4))*a[2]-220/449*a[3]-680/449*a[2]-128/449*(a[1]^4)-(48/449*
     (a[2]^2))*a[1]^4-(32/449*(a[1]^5))*a[2]-(48/449*(a[2]^2))*a[1]^3+(128/449*
     a[2])*a[1]^3-(48/449*(a[2]^3))*a[1]^3+(256/449*(a[2]^3))*a[1]-(32/449*
     (a[2]^3))*a[1]^5-(88/449*(a[2]^3))*a[1]^2-(232/449*a[3])*a[2]+(66/449*
     (a[2]^2))*a[3]+(130/449*(a[1]^2))*a[3]+(24/449*(a[1]^5))*a[3]+(64/449*
     (a[1]^4))*a[3]+(228/449*(a[2]^3))*a[3]+(164/449*a[3])*a[1]^3-(192/449*
     a[3])*a[1]-(256/449*(a[2]^2))*a[1]-196/449*(a[1]^3)+40/449*(a[1]^5)+110/449*
     (a[2]^2)-324/449*(a[2]^3)-18/449*(a[1]^2)+1780/449+(40/449*(a[2]^2))*a[1]^2+
     (32/449*(a[2]^2))*a[1]^5

(along with quite a few bugs that are less critical but seem trivial to fix, like INTERVAL(1..2, 3..4) being displayed as INTERVAL(1..2)).

Are the issues reported on MaplePrimes not being looked into by anyone?
