LinkHighlightingNode: fix X-edge snap unreachable after midY snap

Browse source 
In drawRectsImageContent's modern path the snap loop runs midY
trimming first, leaving rects[i].maxY == rects[i+1].minY for
adjacent line rects. The X-edge snap guard then evaluated
rects[i].insetBy(dx: 0.0, dy: 1.0).intersects(rects[i+1]) — but
positive dy shrinks the rect, so after the trim the guarded
rectangle no longer intersects its neighbor (CGRect.intersects
requires positive-area overlap). Flip dy to -1.0 so the temp
rect grows and touching neighbors satisfy the guard.
