Comment (by tscrim):

 Okay, I've made the offending test return a sorted list. However this
 should be overkill since `index_set` just makes the call to `vertices`,
 which returns a sorted list, into a tuple (i.e. there doesn't seem to be a
 set/dict being returned...). Here's the patches have applied on
 `5.11.rc0`:

 So I'm confused about why we're getting different results, and slightly
 worried.

 Anyways, Ben could you do a quick re-review of the patch? Thanks.
