The
<SummaryBox />
component state will get lost when scrolling to the bottom of a topic. Due to the widget being re-rendered, it will go back to the collapsed state, and we need to fetch the summary again.This change moves all the state updates to the
postStream
model, which also refreshes the widget to keep it updated.
