dialog: $mdDialog.hide( dialogref, "closed" ) closes the last opened dialog instead of the specified dialog

[simonemazzoni]

Actual Behavior:

• What is the issue? * $mdDialog.hide( dialogref, "closed" ) should close the specified dialog passed as first argument, but actually closes the last opened dialog.
• What is the expected behavior? Close the specified dialog!

CodePen (or steps to reproduce the issue): *

• CodePen Demo which shows your issue: http://codepen.io/simomazzoni/pen/YZgdoZ
• Details: Click on LAUNCH DIALOGS ONE AND TWO button, and then clink on 'ONE' ONLY button to see that dialog 'TWO' is closed instead. Same behavior if you open dialog 'ONE' and press 'TWO' ONLY button.

These behaviors lead me to think that $mdDialog.hide() arguments are ignored.

AngularJS Versions: *

• AngularJS Version: 1.6.3 (Same happens also in previous versions)
• AngularJS Material Version: 1.1.3 (Same happens also in previous versions)

Why it happens? Am I doing something wrong?

Notice that these lines of code, seem to confirm my suspects.

Thank you for reporting this. I updated your CodePen. You are right, this example code is incorrect as specifying the dialog reference to close is not supported:

    // Close the specified dialog instance and resolve with 'finished' flag
    // Normally this is not needed, just use '$mdDialog.hide()' to close
    // the most recent dialog popup.
    function closeAlert() {
      $mdDialog.hide( alert, "finished" );
      alert = undefined;
    }

I've opened a PR to remove this confusing example code.

Hello @Splaktar,
so the issue will not be properly fixed?
I mean the behaviour of the old example has been completely removed in newer versions?
May I ask why it has been removed? It looks useful in some situations.

Thanks.
