Single step does not appear to single step

Single stepping doesn't appear to single step. After a second step-over click the left the call-stack shows helloWorld twice, but the yellow bar does not moved. The yellow bar should move to line 22, the "helloWorld" element

After the third click the yellow line moves to the "word" element. At this point the infoset should be populated with an empty element, but the infoset is not displayed nor is the input data.

Not sure that we will be able to do anything about this. The line location information is coming from Daffodil's integrated debugger -- all we are doing is positioning the marker at the indicated location.
The parser constructed by Daffodil is not necessarily a one-to-one match with the schema file.
Just need to check the communication logs and verify that we are, in fact, being given the same location information after multiple steps.
