Minor tweak to .fade:not(.show) to enhance voiceover ability to capture changes as well as remove pointer events from hidden items.
Inspiration taken from https://developer.paciellogroup.com/blog/2018/06/the-current-state-of-modal-dialog-accessibility/
You can see an example working here (i've made some other tweaks to the modal i'd like to test out before raising a PR) https://safari-voiceover-modal.netlify.app/examples/single-modal
