[Vuejs]-Quasar V2 attempting to have LeftDrawer closed on base closed, and hamburger button will open it

The element q-drawer uses several mechanisms to be opened or closed. First and foremost the binding to the variable leftDrawerOpen is essential. You may consider initializing it to false in the setup section. However, as the q-drawer element also contains the show-if-above directive, you should be aware that the state of this variable is ignored for larger screens (see the API docs: https://quasar.dev/layout/drawer). If the drawer should be closed regardless of screen size you should in addition remove this directive.
