Disappointing that there is no progress in regards to this. Edge Legacy used to have overlay scrollbar which still exist in Windows 10 but somehow removed in Edge Legacy. Now we moved to Chromium and nowhere any indication is this coming? The opaque bright scrollbar looks distracting on web page especially if the web page has dark mode feature.
Overlay scrollbar should be an option as well even not as a default since a web page gains few more pixels for actual content without the scrollbar always visible, which I find it unnecessary since I know if the page is scrollable and I use my mouse for scrolling, which I've been doing for more than 20 years since I first got mouse with scroll wheel.
