• Have Glean already configured and a custom tag set.

[Steps to reproduce]:

1. Open the browser with the profile from the prerequisites.
2. Open a new tab.
3. Click the “...” context menu button from a Pocket card.
4. Click the “Dismiss” option.
5. Navigate to the Glean debug page and from the set custom tag verify the latest "newtab" telemetry registered.

[Notes]:

• The issue is also reproducible with the "Save to Pocket” telemetry probe.
• The "format" parameter should be displayed in the "Dismiss" and "Save to Pocket” telemetry probes as per the Test Plan.
• This issue is not reproducible with the sponsored cards.

We can omit from “Save to Pocket” from this requirement/testing. Thank you!

For “Dismiss” - I'd put that as an S4, but if we can fix it while we're on this feature, that would be great.
