Possibly related to Bug 49892, VE is inserting random <span> parameters. See: https://en.wikipedia.org/w/index.php?title=Ruger_P_series&diff=next&oldid=560801075
I can reproduce this against current production VisualEditor/Parsoid on that oldid but not the current id. I'm presuming that this is a Parsoid bug, but not sure of the severity.
That diff is from before we deployed the fix in 49892. And, the oldid html is probably coming from the cache. So, once cache is purged, this should go away. Closing this. Please reopen if still an issue.
