Classes not being added, IE11 do not work at all

[miskowski1]

i've added this to th, when i scroll it stays where it should so it appears to work correctly but default classes weren't added. Even when i use simple div it do not add classes or fire events. I've also tried to add custom classes and this also do not work. It's simply adds position: sticky to element which contains stickybits attribute. On IE11 it doesn't work at all.
