False positives on form submit

False positives are being generated on form submission. Strangely, it is place-based, e.g. the first test, I get false-positives on observables in position 2 & 4, where there are 5 observables that are functionally similar and grouped together.

If I move these around, so that the observables that were in positions 2 and 4 are now in other positions, when i submit I still get false positives in position 2 & 4, while the fields that originally held those positions are now true positives. see: http://stackoverflow.com/questions/39855881/error-with-knockout-validation-validation

Start with the reproduction described in the issue and the linked Stack Overflow example, then trace the form-submission validation path in the repository. No source files or tests are named, so first identify the relevant validation entry point and existing test coverage. Done means equivalent observables validate according to their values rather than their positions, with a regression test for the reported arrangement.
