Luckily, yes.

Same here.  Luckily also, as pointed out elsewhere, the semantics of it
is unclear, so that in several important cases, whichever behavior we
end up choosing will be both correct for some users and incorrect
for others.

Hence, so far, I didn't make any effort to try and "do the right thing"
for user-activated narrowing, since these are just not well defined
enough to even determine what is "the right thing".
