[newbie] ratsimp question

(%i1) trace(ratsimp)$
(%i2) ratsimp(x^g(x^(b+1/b))), ratsimpexpons : true;
1 Enter ratsimp[-1]
1 Exit  ratsimp-1
1 Enter ratsimp[b+1/b]
1 Exit  ratsimp(b^2+1)/b
1 Enter ratsimp[2]
1 Exit  ratsimp2
1 Enter ratsimp[-1]
1 Exit  ratsimp-1
1 Enter ratsimp[g(x^((b^2+1)/b))]     <--- ratsimp applied to exponent
1 Exit  ratsimpg(x^(b+1/b))           <--- revert exponent 
1 Enter ratsimp[x^g(x^(b+1/b))] 
1 Exit  ratsimpx^g(x^(b+1/b))
(%o2) x^g(x^(b+1/b))

Another workaround:

(%i7) scanmap('ratsimp, (x^g(x^(b+1/b))),'bottomup),ratsimpexpons : true;

(%o7) x^g(x^((b^2+1)/b))
