scroll – Google Chrome infinite scroll

I'm using Google Chrome Version 75.0.3770.100 (official version) (64 bits) sure macOS Mojave 10.14.5.

From time to time, web pages end up scrolling Chrome up or down to This seems to happen by chance, I'm not able to reproduce it at will and I do not know if this only happens on pages Web specific or not. Here is a screenshot of gitlab:

This page does not really have space at the top but I can just scroll for ever. When I restart Chrome, I probably will not be able to reproduce it, but in a few days it will happen again.

The only extension I have installed is JSONView which, I think, has nothing to do with that.
