Steps to reproduce


When HTML that uses the Web Notification API is loaded within an iframe, clicking on active notifications causes the host page of the iframe to be loaded in a new tab; regardless of whether a click handler is associated with the notification or not.

This does not happen if the parent page is raising the notification. For instance, in the Steps below, if you open the codepen sample in it’s own page rather then via an iframe the notification click handling is as expected.

Steps to recreate

  1. Go to Microsoft Web Notifications API.
  2. Click the “Send a notification” button.
  3. Click the notification when it appears.
  4. The alert appears, as per the sample code; however, the codepen website is also opened in a new tab.
  5. Remove the Click Handler from the sample JS and click "Send a notification".
  6. Click the notification when it appears.
  7. codepen site appears in a new tab.

    • Hello,

      Thank you for providing this information about the issue. After thorough testing, we are unable to reproduce this problem in Edge with the information at hand. In both test steps you state that codepen is opened in a new tab; what’s the difference and what behavior do you expect? What part of the JS code do you remove in your repro? Please update this case when you can provide updated details.

      Best Wishes,

    • Hello,

      Disregard the previous reply; I can see that you are saying both tests are wrong and the new tab should not open at all.

      I have created https://codepen.io/anon/pen/jLvWmV to use with your repro. We are investigating this now.
