I was looking at https://en.wikipedia.org/wiki/Wikipedia:Database_reports/Long_pages/Draft and came across Draft:PromptArmor, which didn't look like the 574,376 bytes the database reported it should be. The page information view also claims the page to be this size, despite only being a few paragraphs long.

Even weirder, in the page history, it seems like there's a single edit which resulted in a +546,000 bytes change, but all the edit did was to move {{reflist}} up a single line.

When looking at the page source I can't see any reason for the page to be this large. And it seems to actually be this large because it takes a long time for it to load, at least on my computer.
