Doing what?  Making the change or making the change only for whitespace?

Either way, I don't see why the width would make a difference.  What is the
rationale?

Why?  The same jerkiness from alignment change occurs for both positive and
negative, AFAICT.

Try it with a positive width - same thing.

Again, hl-line boxing is hardly typical, I think (again, not at all typical for
my use, at least).  More typical is boxing a word or two.

And one could even argue that that jerkiness was a feature (!) for hl-line mode.
Anyway, hl-line mode should not be important to this - boxing is for many more
use cases than that.

That I would be in favor of.  Simply changing the behavior/appearance without
user choice, I would be against.  Again, just one opinion, of course.
