Every time I use the horizontal scrollbar I get this error:

Aside: while doing git-bisect and reloading the article, I got HUGE whitespace build-up that incrementally got worse:

This was reported for category widget in CX1. After redesign of category widget in CX2, I never saw this happening. This can be resolved.

Huge whitespace reported in T153175#2871848 is something I remember happen to me some time with CX1, but never with CX2.
