Answer 1

Semantic is removing it from your $(this.$el) so next time it does not find it.
It works when you use with global $ and an id:
show(){
const showModal = $('#mymodal')
console.log(showModal)
showModal.modal('show')
}
See Updated fiddle.

Answer 2

If you also want to use Vue variables in your modal, it is necessary to clone the modal and only show the cloned version.
With this approach Vue will still be able to keep track of the original modal, because Semantic doesn't remove it from the DOM.
beforeAdd(){
const modal = $(this.$el).find('.ui.modal').clone()
console.log(modal)
modal.modal('show')
}
