Should the first column here have its top aligned with the second column? Not seeing a mention of this in the specs, but how it looks here feels awkward to me

Breaking changes say

• One Breaking Change - It's required to add fd-list-title inside fd-list-header.

but it's actually fd-list-group-header. And i think the addition of the growing input also would count as a breaking change

@mikerodonnell89 Left column has been changed to be always on top - it's up to example, because on styles we have only left with more than 1 column. So for right it should be at the bottom and left always at top
