Navigation doesn't work after trashing/archiving an email

I think there's no easy fix. Maybe will be like this till the next minor release or longer.

When viewing an email, after selecting the option to trash or archive it, the arrow navigation buttons no longer work. Therefore, your only option is to return to the email list view. The expected behavior would be to navigate to the next or previous email in the folder that the trashed/archived email was originally in. This seems like a bug since the navigation buttons are active and clickable, but nothing happens when you click on them. This is happening in v8.4.0.
