Small cleanup diff to better organize and make the InlineEngagement component easier to read/go through. The two changes to note are
- Renamed threadInfo to sidebarInfo: I thought that this was a more accurate name since this was holding the sidebar thread info
- Reorganized/moved the styles unboundStyles so that the order of the styles went from usage in parent elements/containers to the children elements. Before this the styles were in some random order that didn't make any sense to me
Depends on D8317
