`[autoClose]` for `ngbDropdown` is not working with right click

Bug or feature description:

Right-click does not close ngbDropdown with [autoClose]=true.

<div ngbDropdown
     [autoClose]="true"
     #customContextMenu="ngbDropdown"
     (contextmenu)="$event.preventDefault(); customContextMenu.open()">
           
  <!-- other HTML content -->

  <div ngbDropdownMenu>
    <button ngbDropdownItem>Action 1</button>
    <button ngbDropdownItem>Action 2</button>
    <div class="dropdown-divider"></div>
    <button ngbDropdownItem>Action 3</button>
  </div>
</div>

I'm opening dropdown to imitate a context menu, but when I right-click on another element to also open a context menu, the previous one is not closed. I'm not sure if it's a bug, since you can do something like that:

So maybe it should listen to more events than here?

Versions of Angular, ng-bootstrap and Bootstrap:

Angular: 16.2.12

ng-bootstrap: 15.1.2

Bootstrap: 5.2.3

Start with src/util/autoclose.ts at the linked event-handling logic, then reproduce the two-context-menu example from the issue. Check how right-click events are treated when [autoClose]="true" and verify the expected behavior with the existing dropdown tests. Done means opening another context menu by right-click closes the previously open ngbDropdown.
