Describe the bug

Dismissing a notification using the close button seems to activate the default action. This can be observed with the demo application.

To Reproduce

Steps to reproduce the behavior:

1. Trigger notification
2. Click on the X button
3. Default action is activated (if none specified, this is to launch the application itself)

Expected behavior

Dismissing a notification should make it go away without anything else happening.

Screenshots or screen recordings

In the below recording, I:

1. Dismiss a notification by swiping it away
2. Attempt to dismiss a notification with only a default action, launching the demo app again
3. Successfully dismiss a notification without a default action
