Steps to replicate the issue (include links if applicable):
When I tried to reject a pending changes edit, I believe it stated "Cannot reject these changes because someone already accepted some (or all) of the edits.". However, the changes were rejected by someone else.
Someone at WP:VP/T suggested to file a report on PHAB as it is likely affecting other wikis (fixed on enwiki by QoH).
What should have happened instead?:
I suggest a message change to "some or all of the edits have already received a review" or something along that line.
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia): 1.44.0-wmf.23 (70d5344)
Other information (browser name/version, screenshots, etc.): Chrome on Windows if that matters
