I've added the MdbDropdownModule and MdbTooltipModule to an angular 13 app with Mdb 5.0.0 (mdb-angular-ui-kit-2.3.0.tgz). I even tried with the exact code snippets in the MdBootstrap angular documentation, including the imports in the api docs.

Expected behavior

Tooltip shows on hover and hides when not hovering.

Dropdown in a nav bar toggles a dropdown menu.

Actual behavior

Tooltip shows on hover but doesn't hide when you move the mouse away.

Dropdown shows on click but doesn't hide on click again or when you try to click on another dropdown.

          href="#"
          id="navbarDropdownMenuLink"
