+Current behavior: +
every time a notification gets sent out, the same attachment that is added to the issue the last time is also sent out
+Expected behavior: +
if there is an attachment added during the last operation --> send out the attachment in the notification email
if there is no attachment added during the last operation --> send out the notification w/o any attachment added
If there will be no changes applied to the current behavior, a new, more descriptive name should be drawn up for this option.
