complex-paper-datatable-card.html demo `<dom-repeat>` filter issues

[David-Mulder]

See https://github.com/Polymer/polymer/issues/3094

Can be temporarily fixed by changing line 4195 in Polymer.html to

keys = keys.filter(function (a, i, keys) {
  return self._filterFn(c.getItem(a), i, keys);

So I gather that this needs to be fixed before you implement a filter option in the component?

[David-Mulder]

@moderndeveloperllc: no, this has nothing to do with a generic filter option. Do feel free to open an issue, but it runs down to this:

• in the card you can already filter in any way you like (just trigger retrieveVisibleData after changing your filter)
• in the plain datatable you would need to filter yourself which could maybe be neat to add.

The Polymer developers seem very unwilling to add the array index to the callback for performance reasons. What are the actual consequence to this? I am failing to see the issue! (although it might be completely 100% clear...)
