#17550: sorted variables in multivariate polynomial ring wrong order

We have
{{{
sage: R.<a,b> = QQ[]
sage: sorted([a,b])
[b, a]
}}}
which looks weird to me and is not what one would expect.
This is also inconsistent with
{{{
sage: var('a, b')
(a, b)
sage: sorted([a,b])
[a, b]
}}}
(but in this case the ordering seems always to be alphabetically.)
However, in the multivariate polynomial ring this ordering depends on the
definition:
{{{
sage: R.<b,a> = QQ[]
sage: sorted([a,b])
[a, b]
}}}
