If you try to open a second dialog nothing happens

Do you have any ETA on this ?
This issue broke a lot of features in some of our apps and I can't really use BrowserAnimationsModule instead of NoopAnimationsModule because we have to support IE11.

A side effect of this issue is that MdDialog return the wrong MdDialogRef (from the already opened dialog) instead of the one of the new (but not opened) dialog.

@TomDemulierChevret No ETA for this, but the PR that fixes the issue is ready for merge.

@devversion Nice.
Do you have any idea when it will be merged so I can get the build from https://github.com/angular/material2-builds ?
I will build your branch locally for the moment, but it's not a viable solution.
