Currently resolved comments in pull requests can not be filtered out. In pull requests containing a large two digit number of comments or bigger, there is no longer a good overview as a reviewer and as the developer creating the pull request, which comments have already been addressed or not.

Adding an option to filter out resolved comments (only show unresolved comments) in pull requests would lead to a much better overview of the work at hand and make working in pull requests more efficient, since it removes the overhead of having to scroll through potentially hundreds of comments only to find old, unresolved ones.
