ModalDialogService.showModal() doesn't show modal

[vakrilov]

Issue is reproduced here.

It happens when the following conditions are true:

• showModal() is used in a component that has its change detection strategy set to onPush.
• showModal() is called from an async callback (e.x. setTimeout())

The problem is that when CD strategy is set onPush - we should trigger change detection manually when dynamically loading component (when loading the modal content).
