Any way to capture this in a unit test?

It was tricky to write a test that fails when we expect it to since we trigger the change detection and animations manually.

We can add a type for this while working around Angular Universal's limitations by doing Document|Document

Doing Document|Document fails in AoT.
Error: Error encountered resolving symbol values statically. Expression form not supported (position 84:54 in the original .ts file), resolving symbol MdDialogContainer

Chatted with Chuck and this is a known issue with the metadata extractor (angular/angular#15424). Until that's fixed, we can inject it as any without the private sugar and then manually assign it to the field with type Document.

@crisbeto Can you rebase? |
Captures the previously-focused element immediately, instead of waiting until the animation is done. This fixes a regression from angular#3774, because if we wait for the animation to finish, the focus might have shifted, or the element could have been disabled.
