This is reproducible in the y-prosemirror demo: https://demos.yjs.dev/prosemirror/prosemirror.html

It is to do with how y-prosemirror restores the selection, somewhere around here: https://github.com/yjs/y-prosemirror/blob/7b0a65c20eea7f7da535aef9e08d336c0e07cd24/src/plugins/undo-plugin.js#L86-L89
