Depends, in the original Reddit thread, someone already pointed out that this 5s delay is to wait for some ad thing and then execute code if it doesn’t work within this timeframe. So… depending on what gets cached, blocked, loaded,… it might behave differently on a reload depending on cached data

They found something which waits for five seconds and then does something. At least part of the thing in question was removing some stuff from the DOM - I couldn't understand anything else from the minified JS. That is not a smoking gun.
