snapper is showing this failure too [1], which makes me wonder if it's
a locally-customizable option.

In general, I see no good reason for our regression tests to be making
assumptions about exactly how ICU's root locale behaves, so I'd suggest
just lobotomizing this test case so it doesn't depend on upper/lower
sort order.
