Miri flagged that we borrow a reference to just the first element and then write through it to elements other than the first. The new implementation borrows the whole buffer before writing.

Great to see Miri being added here. :)
cargo miri test will interactively ask for confirmation to install things, and will probably not work. Miri is just not available for the latest nightly so right now we do not enter this code path.
The recommended Miri CI integration is given in our README.

Oh, I like this style... so far I always used #[cfg(miri)] for this but that means we need 4 lines to define one constant.

FWIW, the usual alternative I use these days is #[cfg_attr(miri, ignore)]. Then at least it is clear in the output that we are skipping some tests.
It doesn't really make a difference, though.
