Yes, because the range iteration loop does not add/delete any items.

None of the conditions specified in that clause applies for updating key
in-place. The way I read it, a new entry is not added, so the iteration
should visit every entry only once. Thus, the program always prints "1 1".

Hello Go gurus,
I think there is some ambiguity in the language spec about what happens
when a map entry is updated during iteration. Quoting the spec
(https://go.dev/ref/spec#For_range):
3. The iteration order over maps is not specified and is not guaranteed to
be the same from one iteration
