Firefox mobile Bottom navigation lag

[Kos-M]

Hey , i am using this lib at the bottom of my page , but when i have bottom navigation bar enabled on mobile firefox when the page is in full screen mode the animation is glitching.

Is not smooth at all.

Tried different browsers bottom navigation. Seems only in firefox this happening .

If someone really want to see it in action i can provide a url to see it in action. Just comment me bellow .

Thanks..
