When I visit a folder with, say, one unread message, and then read the message, the folder name remains in bold and the count of unread messages isn't decremented immediately as it used to be. The unread count and bold typeface sometimes are not updated until I leave the folder. Happens with both IMAP and local folders. In preferences, I have "Automatically mark messages as read, Immediately on display." Reproducible: Always Steps to Reproduce: 1. In preferences->advanced->reading & display, check "Automatically mark messages as read, Immediately on display." 2. Visit folder with one unread message 3. Read the message. Notice that the folder name is still displayed in bold face and the unread count still says "(1)". 4. Visit a different folder and notice that the previous folder's unread count is now brought up to date. Actual Results: Unread status wasn't updated immediately as it is supposed to be. Expected Results: Unread status should be updated as soon as message is read.
