angular - How to make Material Design Menu (mat-menu) hide on mouseleave

I succeeded in making the menu appear on mouseenter. What I want to do now is make it disappear on the mouseleave event of the menu itself. Any ideas on how to make this possible?

    <button mat-button [mat-menu-trigger-for]="menu" 
     #menuTrigger="matMenuTrigger" (mouseenter)="menuTrigger.openMenu()">
        TRIGGER BUTTON
    </button>
    <mat-menu #menu="matMenu" [overlapTrigger]="false" 
     (mouseleave)="menuTrigger.closeMenu()">
         <button mat-menu-item [routerLink]="['sources']">
              <mat-icon>view_headline</mat-icon>
              MENU CHOICE
        </button>
    </mat-menu>

You can do this by wrapping the menu buttons in a <span> element:

HTML:

<button mat-button 
  [matMenuTriggerFor]="menu" 
  (mouseenter)="openMyMenu()">
  Trigger
</button>
<mat-menu #menu="matMenu" overlapTrigger="false">
  <span (mouseleave)="closeMyMenu()">
    <button mat-menu-item>Item 1</button>
    <button mat-menu-item>Item 2</button>
  </span>
</mat-menu>

Component:

export class MenuOverviewExample {
  @ViewChild(MatMenuTrigger) trigger: MatMenuTrigger;

  openMyMenu() {
    this.trigger.openMenu();
  } 
  closeMyMenu() {
    this.trigger.closeMenu();
  }  
}

well, this solution is good, however there is a bug. if you click the button,  open the menu and not hover over menu, you can close it with no changes for the button. If my button has an extra class to show that this button is active, it is a problem then.
