Scroll issue with solution #25

Closed DimitriLib closed 4 years ago

DimitriLib commented 4 years ago

Using directive with datasource, virtual scroll works great. But experiencing issue with keyboard navigation (Arrow Up/Arrow Down) and scrolling of the contents. We have mat table with sticky headers. To reproduce, first scroll down with arrow keys so first 5 rows would disappear from the viewport, then start scrolling up. Once top visible row reached, contents is not scrolled, but almost feels like it counts header row as a part of the visible scroll area. It feels that scroll is one row behind because of counting of the header row as a part of visible scroll.
