So I never asked for NBSP to disappear. I said I want it to *stretch*.
And to my mind "stretch" means to become wider than one's normal
width. It doesn't include decreasing or disappearing width.

I don't expect NBSP to ever disappear, because spaces disappear only
at linebreaks, and NBSP simply doesn't stand at linebreaks.
