4. See that note start is not on grid, a bit earlier or later.
5. Snap left edge of item to grid and glue.
6. Now see on notes like in p.4 - they now start on grid.
This is not actually a bug: As per MIDI specifications, MIDI events can only fall on discrete tick positions, counted from the start of the item. So if your item does not start on a grid position, the ticks *inside* the item may not correspond to the project's grid.
