Subsequently, you unmask the prescribed mail in the current folder as Junk (see precondition) Steps to Reproduce: 1. See if there's a mail being marked as junk which contains a an event notification. 2. Select another arbitrary mail 3. Mark the mail mention in 1 as not Junk. Expected Results: I would have expected not to receive the new e-mail notification. Actual results: The currently shown mail (in the "mail" windows) will not change, but an event notification panel pops up. It says, this message contains ..., which is definitely not the case. Reproducible: Always Expected results: Either the shown mail should have changed or the event notification panel should not have popped up.
