Thanks Anna,
Another workaround we found for this issue was bringing in chatter through an iframe in the skuid page. This presents other sizing issues, and displays the classic chatter view vs the lightning chatter interface, but it was a better solution for our use case because it allowed us to keep chatter within the skuid page. Here’s the iframe configuration for chatter if it’s helpful for anyone else:
<iframe frameborder=0 width="100%" height="800px" src="/apex/skuid__Social?id={{{AccountId}}}"/>
