Note that x^(1/log(x))=e. Why won't this expression simplify?

syms x a;
assume(x>0)
x=exp(a)
x = 
simplify(x^(1/log(x)),'IgnoreAnalyticConstraints',true)
ans = 
e

Hi,
have you tried increasing the number of simplification steps?
>> simplify(x^(1/log(x)),'steps',10)
ans =
exp(1)

The answer to your question is clearly 'no'! It seems crazy that you have to do that for such a simple expression.
Thanks
