Andrew and Kaede, I did check with our engineers about this behavior (where users are being redirected to a new page to comment on a Chatter post). They explained that the behavior is determined by the Chatter component (which is a Lightning/ Salesforce component), and we don’t have any ability to reach in and change the click behavior. The fact that it’s behaving differently may be because the component is making calls from inside the Skuid component or namespace, or something along those lines. So, depending on your use case, you may opt to put your Chatter feed in its own Lightning component, along side the Skuid Page Lightning component.
