Mail 11 (High Sierra): mail attachments "downloading" but never actually download

Since my upgrade to High Sierra, I can't download, read, quicklook ..... almost any attachments.

Especially PDF documents are problematic. It shows a light blue sign "Dowloading" under the file icon.

MacBook Pro (15-inch Mid 2012), macOS High Sierra (10.13)

Any emails with attachments that come into a smart mailbox will exhibit the "downloading" problem. If I access the same email in its regular inbox, the attachment downloads without issue. So add "smart mailboxes" to the bug pile. Are you listening Apple?
