Summary:
Currently, draggable lists (in Config and ApplicationSearch, for example) don't let you drag an item into the first position.
This is because the behavior is correct in Maniphest: the first position is above an initial header, like "High Prioirty", and shouldn't be targetable.
Permit the behavior in general; forbid it in Maniphest.
Test Plan:
- Dragged elements into the first position in ApplicationSearch.
- Failed to drag elements into the first position in Maniphest.
