Bad things happened here: https://en.wikipedia.org/w/index.php?title=Jack_Parsons_%28rocket_engineer%29&diff=604788783&oldid=604787564 The editor made changes to one paragraph. About 1400 spaces were added to over 100 templates, so that this: {{sfn|Pendle|2005|pp=201, 304}} became this: {{sfn|Pendle|2005|pp = 201, 304}}. In a quick review, only {{sfn}} and {{snfm}} templates were adjusted, and they were only changed if they contained an equals sign (=).
Sounds like a Parsoid bug. There was no check tag on the revision, so it's very unlikely VE had anything to do with it. I tried to reproduce this by editing the version right before this diff, but I couldn't reproduce. A new version of Parsoid was deployed just 30 minutes prior, though, so maybe that fixed it.
