Failed to restore banked assessment with xAPI

[lars-moch]

I had a course with an assessment that uses question banks (AT: 0.10.5, FW: 5.18.4).

It worked as it should when I used SPOOR but when I switched to xAPI, there seemed to be a problem:
If I return to a passed assessment in a new session, it no longer shows as completed in the menu.

I made a miniature course to isolate the issue.
It has just one page with an assessment with 6 questions in 3 banks (two questions in each bank).
My split is "1,1,1".

When I return to the course in a new session after passing the assessment, the assessment article is not completed, even if the question components and their blocks are completed (or this is at least how it looks when I use the course map in the Kineo Developer Tools).

After some investigation, the problem seems to be that when restoring the completion status of the assessment article, it considers all 6 questions in the article - not just the ones that were drawn.
This causes the assessment article to be set as incomplete, as the remaining 3 questions are all incomplete.

When using the SPOOR/scorm extension, it seems to restore the assessment status with regards to the questions drawn.

I am using the adapt-contrib-xapi version 0.9.5.
