If it appears before the open brace in column zero, yes.

It would still only get as far as to the next brace in column zero.

No.  Fast and imprecise scrolling doesn't improve anything either here.
I'm surprised how people get improved behavior from these.  But I agree

conduct an in-depth analysis of this problem and spotting a possible
culprit without such an analysis is, in fact, futile.
