paper-select: performance issue with lots of options

I currently have a little performance issue with a `paper-select` that have ~130 options.

Because all options are rendered in DOM it takes ~180ms for the menu to be displayed when the user clicks on it.

And because the search re-render everything instead of toggling elements visibility using css, each keystroke have a ~180ms latency.

Not sure if `ember-paper` should render the options the same way as it does with autocomplete or if there is a way to easily implement this feature on top of paper-select.

Any thought?
