Problem:
Resetting w_scbind_pos to the displayed position discards pending
scroll distance. This breaks scrollbind with asymmetric folds and
leaves persistent offsets after tall virtual-line blocks. Wrapped
lines with smoothscroll also show increased follower lag.
Solution:
Revert the original change and its test. This restores the previous
behavior, including the original tall-virt_lines oscillation, while
a replacement is reviewed separately.
This reverts commit b781e95a24.
