6.1p ListGrid different behavior between fetchData(advancedCriteria) and setInitialCriteria(advancedCriteria)

[Blama]

Hi Isomorphic,

I noticed a strange issue when accidentally using fetchData() with Criteria instead of AdvancedCriteria and manually filtering afterwards.
Trying to create a testcase before noticing the mistake, I found this different behavior fetchData(advancedCriteria) and setInitialCriteria(advancedCriteria) with v11.1p_2017-12-05.

In this BuiltInDS-based testcase, the inital fetches are textMatchStyle:"substring" for initalCriteria and textMatchStyle:"exact" for fetchData().
The fetches itself are fine and the same, which is expected.

Further filtering for "Ad" in the Item column issues a request in the 1st ListGrid (loaded with fetchData()) but does not in the 2nd (loaded with initalCriteria and autofetchData), which does client-side filtering.
I don't see the reason for this and would expect both filter actions to be client side only.
Perhaps the error is only the used textMatchStyle. Here I don't know why they differ.
