Offcanvas is not dismissed, starts to stack

Bug description:

When hooking this function to a button that can be clicked multiple times the offcanvas is only closed and opened correctly once. After that the offcanvas elements start stacking over each other:

closeThenOpenDrawer() { this.offcanvasService.dismiss(); this.offcanvasService.open(OffcanvasDrawerComponent, { backdrop: false, position: 'bottom' }) }
