Reselection fails in chosen

In Essentials, Dashboard Wizard Plugin configuration screen, I have a few chosen dropdowns, and noticed that some of them don't work when I change the selection. The relevant HTML code is

<select name="selectedDocument" chosen
ng-model="selectedDocument"
ng-selected="selectedDocument"
ng-required="true"
ng-options="option.fullName for option in documentTypes"
data-placeholder="Document type"
width="'100%'">
</select>

It appears that whenever the ng-model value on the scope is set to , the selection is off by 1 (select index x, get index x+1) upon changing the initial selection. mlenser found a chosen issue for this:
