Created attachment 386435 [details] Example test case Steps to reproduce the problem: 1. Access the HTML file attached 2. Scroll down a bit 3. You'll see how the page scrolls down automatically fired by JS but the scrollbar is not visible while doing so. What is the expected behavior? The scrollbar should always be visible no matter how the movement gets fired. No matter if it is a user input or if it is fired by the code. What went wrong? The scrollbar is not visible while the page gets scrolled. Reported originally at crbug.com/985801
