Input from Gemini 3.1 Pro:
✦ Now that the new
ScrollSyncgranular locking mechanism handles event feedback loops correctly (even during rapid programmatic momentum updates), we no longer need to restrict two-way synchronization.I've removed the
hasMouseEventscheck fromsrc/grid/VerticalScrollbar.mjs. It now unconditionally registers fortwoWay: true.This unlocks the ability for users on touch devices to physically grab and drag the native scrollbar thumb to scrub through massive datasets!
This ticket is complete.

Part of Epic #9369
Update
src/grid/VerticalScrollbar.mjsto remove thehasMouseEventsrestriction when registering withScrollSync. It should unconditionally register fortwoWay: truesynchronization, now that the underlyingScrollSyncaddon is loop-safe via the new locking mechanism.
