Describe the feature

There doesnt seem to be a prop to control if the Dialog should get removed from DOM or not (e.g. by using v-show instead of v-if).

Coming from vaul-vue, our project requires to have the content of the drawer to be part of the DOM at all times for SEO reasons. For SEO it can be absolutely crucial if specific content is missing, e.g. if the menu is in Drawer it will never be rendered for crawlers.
