When pinning a discussions, the discussion appears pinned at the beginning of the discussion view, as you'd expect from the name of the feature.
However, one side-effect of post pinning is that the modification time of the post is also updated.
This is arguably correct, however when you then unpin the post it also updates the modification time which has a knock-on effect that the post continues to appear at the top of the discussion list, rather than to jump back to the time at which it was originally written.
This has been raised in MDL-58758 and I'm interested to see whether the consensus is that the time should, or should not be modified when pinning and unpinning a discussion.
Thanks in advance,
