It turns out the way I was including jQuery was causing issues with Tampermonkey and Violentmonkey, which I never noticed because I was using Greasemonkey. It should work correctly with all three extensions now.
Oh ok seems you fixed it, nice. Also when using it with Unlimited Paginator Works the script doesn't update so when you scroll past the first page the hover just doesn't work anymore.
Fixed.
For whatever reason the script disables tab autocomplete.
