Description

The implementation of the fn:innermost function is designed to avoid sorting the argument sequence into document order if it's statically known to be already sorted. However (in 9.8 and 9.9) this optimization isn't working: the "presorted" flag is never set (except when loading from a SEF on which it is already set), and the sort into document order always takes place.
