Description
#### Bug, feature request, or proposal:
Bug
#### What is the expected behavior?
Menus open and stay open until dismissed
#### What is the current behavior?
Menus open for a split second and then disappear
#### What are the steps to reproduce?
This is only on 7.0.0-beta.0, I need a starter stackblitz for that version. Any basic menu should reproduce it.
#### What is the use-case or motivation for changing an existing behavior?
#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?
7.0.0-beta.0
#### Is there anything else we should know?
The issue goes away if you use lazy rendering, ie. `ng-template` with `matMenuContent`.
