Expected behavior

I'm trying to use the fixed buttons to be active on click as shown in the docs: https://mdbootstrap.com/docs/angular/components/buttons/#fixed-buttons (Active on click)

Actual behavior

If you click twice on the main button (the double click event is fired) the secondary buttons don't hide from the view, instead they are shown on top of the main button

Resources (screenshots, code snippets etc.)

Code: https://mdbootstrap.com/docs/angular/components/buttons/#fixed-buttons (active on click section)

Result (after a double click): https://ibb.co/v100hh1
