ScrollViewer: Users cannot hold the mouse wheel to pan #9818

Describe the bug

A common scroll interaction is holding the mouse wheel to pan vertically or horizontally. For example, the continuous scroll pattern used by websites or the click & drag pattern used by touch. WinUI 3 ScrollViewers only support vertical panning by scrolling the mouse wheel, clicking & dragging the scroll bar anchors, or hold & dragging with touch. Hold & drag is not supported with mouse (left button or mouse wheel hold).

Steps to reproduce the bug

  1. In an scroll/zoom enabled ScrollViewer (e.g. from the WinUI 3 Gallery), use Ctrl+Mouse Wheel to zoom in such that there is room to pan both vertically & horizontally
  2. Press & hold the mouse wheel over the zoomed content, drag the mouse in various directions

Expected behavior

The zoomed content pans within the ScrollViewer according to the direction of movement Actual behavior: nothing happens, content also cannot be panned by holding & dragging with the left mouse button
