Selection gestures now treat releases with invalidated anchors as dragged,
so a press that crosses screen boundaries cannot also activate links or
prompt clicks on release. Cell drags that create a same-cell selection also
mark the gesture as dragged, which keeps click-only actions from firing
after a threshold-crossing drag.
Autoscroll now resolves the drag pin after moving the viewport instead of
reusing the pin from before the scroll. This keeps the selection aligned
with the row currently under the pointer. The inspector also validates the
tracked click pin before displaying it so stale pins from inactive screens
are ignored.
