+    Counts the number of times the user swiping on the system tray to open /
+    close the system tray bubble.

This description is not entirely accurate since the metric is only recording
instances where the user has swiped up on the tray in an attempt to open the
bubble. My suggestions here would be to:

* Re-name UMA_STATUS_AREA_SYSTEM_TRAY_SWIPING to
UMA_STATUS_AREA_SYSTEM_TRAY_SWIPE_TO_OPEN or similar

* Re-name StatusArea_SystemTray_Swiping to StatusArea_SystemTray_SwipeToOpen or
similar

* Re-word the description as "Records when the user swipes up on the system tray
in an attempt to open the system tray bubble. Note this is recorded even if the
bubble is not opened, i.e., if the swipe was too short." [1]

In a follow-on CL you can add a separate metric
StatusArea_SystemTray_SwipeToClose.

[1] If you wanted to be super-precise, you could count two things separately:
instances where the user started to swipe up but the menu didn't open, and
instances where the user started to swipe up and the menu opened. I think it is
ok as-is, but perhaps run this by a PM to see exactly what metrics they care
about.

OK. Let's keep it as-is first. Just waiting for the response from the PM.

     Shortcut added to the homescreen with a valid Manifest. This action will be
     recorded in addition to AppShortcut, AppShortcutApple and Bookmark actions
     to keep a trend of whether the webapp also add meta tags.
