Thanks for working on this, but I'd rather fix the comparator used while sorting, rather than disable the check. We would have to fix it anyway when Apple will remove the disabling flag. I'll try to pull some more people on this issue to get their perspective. |

Summary:
Fixes assert crash in #46568 (comment).
We can temporarily downgrade _LIBCPP_HARDENING_MODE to _LIBCPP_HARDENING_MODE_EXTENSIVE, it disables strict weak ordering check in debug mode. Actually, when we sort animation mutations, we don't need it to satisfy strict weak ordering.
https://libcxx.llvm.org/Hardening.html#id3
Another solution is we make sort satisfy it, but we don't have any key to compare when two mutation is the same mutation type but not the same parentTag. Maybe we can use pointer of muation to compare?
