Fix resizing nodes not respecting the drag-start

Resizing nodes used the cursor location when the event was triggered
instead of the drag-start, harmless but means the drag location isn't
under the cursor especially with a high drag threshold.

Noticed when investigating other drag issues,
unrelated to recent changes to drag behavior.
