Given a tracker with field dependencies defined between selectbox / multi-selectbox fields, and given list-picker is not disabled with a feature flag for this tracker, when I create or edit an artifact of that tracker and I select a "source" value, then the "target" value will no longer be automatically selected. I must click to open the target field and click again to choose a value.
When there is only one possible value (as configured in field dependencies), then it should be selected when I select the corresponding "source" value. This saves me two clicks.
This was introduced by git #tuleap/stable/a4aa0b4475ef5ddb6cd95d689c3252db4cedf94b. list-picker used to select the first available value by itself, but this behaviour is desired only in tracker field dependencies context. It causes problems everywhere else. Thus, it was removed. We should instead edit the "field dependencies" javascript code itself so that it auto-selects target values.
