Describe the bug

Imagine we have an app that when the user attempts to close displays a content dialog to confirm if the user really wanted to close the application and in turn lose the work.

In this application there is a teaching tip to help user understand the application little better.

When the user invoke the teaching tip and attempt to close the application after that.

1. teaching tip is not dismissed even when light dismiss mode is set to true.
2. the content dialog that is displayed is displayed, is shown behind the teaching tip.

Steps to reproduce the bug

1. Click on a UI control to invoke a teaching tip (light dismiss mode enabled)
2. Click on the app close button (it invokes a dialog box if the user wants to quit the application)
3. Teaching tip is not dismissed
4. The content dialog is shown behind the teaching tip, not allowing the use to close the application or read the message properly.

Expected behavior

1. If the light dismiss mode is set, when user click the close/maximise button the teaching tip should be dismissed
2. The content dialog should always be shown on top of the teaching tip.
