Description

Tested with http://ui-grid.info/docs/#/tutorial/203_pinning on Windows 10, Edge Browser 20.10240.x and IE11.0.10240.x

If you have a pinnedLeft column you can only scroll-y on the non pinned container.

When you have a pinnedRight column, you are no longer able to scroll-y when hovering over the other columns (other ui-grid-viewports), only in the pinnedRight container. And if you scroll-y in the pinnedRight container, the other container rows are jittering (scroll and render slower than the pinnedRight ones).

Horizontal scroll works (but the header columns have a slight render tearing, tolerate-able).

Research direction
Investigate the scrolling behavior in pinned column viewports. The issue describes that vertical scrolling only works on non pinned container when left pinned columns exist, and that right pinned columns cause jittery rendering. Check the core scrolling logic in ui grid, particularly the 'ui grid viewport' directives and scroll event handling. Look for any recent changes or similar bugs reported. Since the issue is old, test in modern browsers to see if it persists. Consider using virtual scrolling implementation details in the source code.
