Jump to previous / next message inconsistently marks messages as read
I use the ,
and .
shortcuts to jump to the previous / next messages in my mail account, and noticed the marking of messages as "read" had a problem when jumping to another folder.
Messages are correctly marked as read after the configured delay (which I reduce to 0.2 seconds in my config) when jumping within a folder, but as soon as all messages are read and you jump to another folder, the first message landed on never gets marked as read, unless you manually click it or otherwise get the timer to reset somehow.
