Can't you see it in sources? =) clientHeight of ScrollbarsCustom-Content element.

mistake when you switch to mobile mode in chrome, the scrollbar height begins to increase infinitely, the same is observed in Firefox when zooming

@AlekseevKonstantin could you provide any snadbox example?

As far as i can see, you've enabled sizes translation without any height restriction and set display:flex to the content element, so block height rises infinetely
