From my few years of experience working inside the team(now retired) just keep on plugging away, try to address comments but also understand them and be open to a polite debate with reasons for the choices made. What may seem like blocking comments, rarely are if you make sound points and contribute good code.

Update the PR with any reviewer comment requests and bump it after a couple of weeks with a reason I.E. a commit squash or code update. If its languishing for no reason, ask the team why and what can be done to improve it or ask them to close it if not. If it is closed, try another approach. The key is to stay positive and work around any issues.
