Mobile: Click event is fired when Nested MatMenu is hidden

[hisomu]

What is the expected behavior?

In mobile, clicking anywhere on the parent navigation mat-menu should only execute the sub menu. Then click on the submenu, with a routerLink, to see another page.

What is the current behavior?

In mobile, if the sub-menu overlaps the parent mat-menu the routerLink in the sub-menu gets executed, even when the sub-menu is hidden.

What are the steps to reproduce?

In a mobile device go to: https://angular-aor8v8.stackblitz.io/
Source: https://stackblitz.com/edit/angular-aor8v8?file=app%2Fnested-menu-example.html
Example: http://recordit.co/JopTv4JWTU

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Angular 7.1.1
Material 7.1.1
Chrome

Is there anything else we should know?

I tried the lazy rendering with matMenuContent and it didn't seem to have any affect.
Also, tested on an iOS device and it works perfectly fine

Via device toolbar it's reproducible on desktop too.

I don't think I get what the issue is exactly. Can you post a step-by-step on how to reproduce it?

@crisbeto Steps for Chrome on desktop

1. Open https://angular-aor8v8.stackblitz.io/
2. Open developer tools and switch to a small device. e.g Galaxy S5
3. Click 'Site Index'
4. Click at the marked spot

Instead of the submenu CNN opens.

Am I just facing this in a weird context or is this actually still happening? Handling a click on a submenu that gets executed immediatelly on showing the submenu if they overlap (mobile).

Edit: in case the Angular Team (or anyone else finding this) is interested: in my case removing an @if around the element containing the matMenuTriggerFor solved the issue.
