[SalesForce] Force:recordView and Force:recordEdit broken in Winter ’17

All,

I've been developing Lightning Components and get an error in Winter '17 whenever I try to use force:recordView or force:recordEdit:

Something has gone wrong. afterRender threw an error in

Please try again.

I've noticed that the root of the error seems to be that ui:tooltip, which the Winter '17 documentation implies may no longer be supported?

Introducing Base Lightning Components – Bottom of the page

I've tried using them in components/apps with multiple components and I've also tried to use them on their own in an aura:application, just to test them:

<aura:application extends="force:slds">
   <force:recordView aura:id="details" recordId="0034E00000Az9OV"/>
</aura:application>

I've found that the component will work if you include type="MINI", but adding/removing "extends=force:slds" doesn't seem to make a difference, so the issue appears to be with the tooltips on the full page.

Can anybody confirm if these components are currently broken?
