Thank you, @SergeiSomin. This is related to

ui/src/ScrollBox.ts

Line 490 in b3b2fa6

 protected onMouseScroll(event: WheelEvent): void 

I think it would be enough just to add there a check for the size of the inner view size and skip scrolling if if is less than scroll box size. Do you want to make a PR?

[Barkas]

Yeah, got it, thanks, I will do PR
