First mode to appear on mobile dropdown.

I thought this was an issue with the app but it looks to be a mobile web issue..

It seems to be limiting the drop down options to only three.

I'm running 0.59.1 with iPhone 7 on iOS 11, happens through the iOS HA app as well as Safari.

I am seeing this with the Roku component as well on mobile. Can't access the top few items on the input list.

I tried Safari emulator and I could not reproduce on 0.60. Is this only visible on devices?

Still same problem.

This seems to be a bug with Polymer PolymerElements/paper-dialog-scrollable#72

Let's track this in home-assistant/frontend#775.
