I'm finding I can't use the same object in a v-repeat more than once in a vm---it has a reference to some flavour of it as it manages to iterate the right number of times but only has access to the properties (or keys) the first time through.

If I nest it in another v-repeat I can use the same object again (once), presumably because it gets a new vm.

By contrast, arrays seem to work every time. Here's a fiddle:
