Describe your issue

Running npx @tailwindcss/upgrade in order to upgrade to v4 in our Vue project also renamed the blur event name to blur-sm in the following sample within the <script> block.

editor.value.view.dom.addEventListener('blur', () => {
  emit('blur')
})

After the automated migration:

editor.value.view.dom.addEventListener('blur-sm', () => {
  emit('blur-sm')
})
