"Select on list" for "open action" does not put Thunderbird in foreground (Windows 10)

I chose "Select on list" as the "Open action" for "New message notifications". When I click the notification on Windows 10, it selects the message in the list, but does not put the Thunderbird window in the foreground and activate it.

If I chose the default "Open new tab" instead, Thunderbird correctly gets taken to the foreground and activated.

This seems like a bug to me, or am I misusing the extension?
