The RegExp checking if a localStorage key belongs to the collection being cleared checks whether the key simply contains the collection's name, and not if it begins with it.
So if when clearing a collection named items, it will also remove the localStorage keys for dictionaryitems.
Instead, we should check the key starts with the name:
(new RegExp "^#{@name}").test(key)
This had me scratching my head for days wondering why localStorage was magically losing data before I narrowed it down :)
