Remove a `FIXME` comment.
It is possible to avoid the clone as suggested in the comment. It would require introducing an enum with two variants `CloneBeforeModifying(&Domain)` and `Modifiable(&mut Domain)`. But it's not worth the effort, because this code path just isn't very hot. E.g. when compiling a large benchmark like `cargo-0.60.0` it's only hit a few thousand times.
