Panic because sorting function doesn't implement total order #5783
Description
We seem to have a panic in the codebase because one of the functions we pass to sort_by() doesn't implement a total order.
A sentry report was sent to use with the following message:
user-provided comparison function does not correctly implement a total order
Sadly the stack trace doesn't really tell us much which function in our codebase called the sorting function.
I attempted to guess which one it could have been in #5782 but the recency sorter seems to be fine.
