Custom scroll doesn’t work with trackpad on macOS

[vitalytalyzin]

Hello. When using the scroll on the trackpad in Chrome on macOS Catalina 10.15.4, default scroll bars appear, the custom scrollbar doesn't work and tracks have display: none style. But when you turn off the trackpad or set the global -webkit-scrollbar styles, like body::-webkit-scrollbar { width: 10px, height: 10px;}, everything works fine. Have anybody face this kind of problem and how did solve it? Is it possible?

Yes me too. Vertical track gets a display: none, and thumb doesn't even get a calculated height.
