I noticed a couple of instances of this in mwlog1001:/srv/mw-log/exception.log this morning.
2019-11-18 14:46:41 [XdKuzwpAIDQAAJVttjcAAADX] mw1340 commonswiki 1.35.0-wmf.5 exception ERROR: [XdKuzwpAIDQAAJVttjcAAADX] /w/api.php MediaWiki\Extension\MachineVision\MachineVisionEntitySaveException from line 148 of /srv/mediawiki/php-1.35.0-wmf.5/extensions/MachineVision/src/Handler/WikidataDepictsSetter.php: * Your edit was patched into the latest version.

The error message being logged is Your edit was patched into the latest version., which comes from Wikibase and indicates a successful attempt to resolve an edit conflict. This is added to the EditEntity result Status as a warning (code), which should not cause Status::isOK() to return false. Yet Status::isOK() is returning false here, so there must be something else going on as well.
Steps to Reproduce: TBD
