Jak525's post in TWS MAN does not slew the B Scope to the TDC was marked as the answer
Spotlight should work in TWS. The new behavior is correct for MAN centering. The previous mechanization was wrong. The scan center is defined by depressing/releasing the TDC. It does not follow the cursor. The only "cursor following" mechanic is Spotlight.
TL;DR no bug, MAN was fixed this patch, it was wrong before
